• Hierarchically Structured Porous Polyamide‐Imide Membrane for Switchable Emulsion Separation

  Abstract The development of advanced membranes with switchable superwettability has attracted considerable attention for the efficient treatment of oily wastewater. However, challenges persist in designing and fabricating such membranes through straightforward methods. In this study, a novel strategy is presented to design switchable superwettable membranes based on micro/nano‐structured porous surfaces and surface chemical composition reorganization. A commercial amphiphilic polymer, polyamide‐imide (Torlon), is fabricated into a porous symmetric membrane with a hierarchical surface structure using a one‐step non‐solvent‐induced phase separation method. By leveraging the surface reorganization capability of amphiphilic polymers and the hierarchically porous structure, the resulting membranes demonstrate exceptional superamphiphilicity in air, underwater superoleophobicity, and underoil superhydrophobicity. These properties enable ultrahigh permeance and separation efficiency for oil‐in‐water, water‐in‐oil, and crude oil/water emulsions through a gravity‐driven process, eliminating the need for external energy. Furthermore, the membranes exhibit excellent antifouling and self‐cleaning performance, maintaining stable operation over multiple cycles. This work provides an innovative and scalable approach to next‐generation switchable superwettable membranes with broad potential applications in oily wastewater treatment and beyond.

• Zinc-imidazole-based metal-organic framework nanosheet membrane for H2/O2 separation

  Shunsuke Tanaka, Yuka Kimura, Kojiro Fuku, Naoki Ikenaga, Keizo Nakagawa

  Abstract Metal-organic framework (MOF) nanosheets are promising candidates for molecular sieve because of their structural diversity and minimized mass transfer barrier. However, design of appropriate MOF nanosheets and preparation of high-performance MOF nanosheet-based membranes, especially for gas separation, remains great challenges. Structural degradation may simultaneously occur with conventional exfoliation method, which has hindered its widespread application in high-performance molecular sieve membrane preparation. Even if nanosheets could be stacked, grain boundaries would form between the nanosheets, which could be applied to liquid separation but not to gas separation. To address these challenges, we applied bottom-up growth of Zn2(benzimidazole)4 nanosheet to fabricate defect-free membranes. Zn2(benzimidazole)4 is composed of benzimidazole-zinc tetrahedral units and layers are connected by van der Waals interaction. At first, the Zn2(benzimidazole)4 nanosheets were deposited onto a porous support to prepare gutter layer. Next, Zn-based amorphous layer was coated on the gutter layer and crystallized by benzimidazole vapor treatment. Highly oriented Zn2(benzimidazole)4 nanosheet based membranes were fabricated by anisotropically controlling crystallization. The prepared Zn2(benzimidazole)4 nanosheet-based membranes show separation performance in hydrogen purification with H2/O2 ideal separation factor of 11.6 and H2 permeance of 5650 GPU.

• Self‐Aggregation Control of Porphyrin for Enhanced Selective Covalent Organic Network Membranes

  Zheng Wang, Keizo Nakagawa, Kecheng Guan, Mengyang Hu, Zhaohuan Mai, Wenming Fu, Qin Shen, Yasunao Okamoto, Atsushi Matsuoka, Eiji Kamio, Tomohisa Yoshioka, Hideto Matsuyama

  Abstract Covalent organic networks (CONs) are considered ideal for precise molecular separation compared with traditional polymer membranes because their pores have a sharp molecular weight cut‐off and a robust structure. However, challenges remain with regard to tuning pores as a prerequisite for facile membrane fabrication to a defect‐free layer. Herein, a highly conjugated amino‐porphyrin is used and exploited its tunable stacking behavior to fabricate porphyrin‐based polyamide CONs with ordered structures through interfacial polymerization with acyl chlorides. Controlling the self‐aggregation behavior of the porphyrin and the conformation of the acyl chlorides can create different covalent networks. Acid‐triggered porphyrin protonation offsets stacking to reduce the pore in the network from mesopore to micropore, enabling selective molecule transport. Furthermore, different acyl chloride ligands are used to control the interlayer bonding in CONs. Accordingly, the tailored pore diameters (0.48–0.78 nm) are confirmed by the molecule rejections with performance stability over 25 days of operation, as well as under various conditions. This study leverages porphyrin chemistry and interfacial polymerization to fabricate a defect‐free CON layer with a significantly lower molecular weight cut‐off (< 330 Da) than previously reported porphyrin‐based membranes (>800 Da). This will pave the way for the development of ideal topological membranes.

• Nanochannel Stability of Chemically Converted Graphene Oxide Membranes

  Siyu Zhou, Kecheng Guan, Zhan Li, Ping Xu, Shang Fang, Aiwen Zhang, Zheng Wang, Shengnan He, Keizo Nakagawa, Hideto Matsuyama

  Abstract Chemically converted graphene oxide laminate membranes, which exhibit stable interlayered nanochannels in aqueous environments, are receiving increasing attention owing to their potential for selective water and ion permeation. However, how the molecular properties of conversion agents influence the stabilization of nanochannels and how effectively nanochannels are stabilized have rarely been studied. In this study, mono‐, di‐, and tri‐saccharide molecules of glucose (Glu), maltose (Glu2), and maltotriose (Glu3) are utilized, respectively, to chemically modify graphene oxide (GO). The aim is to create nanochannels with different levels of stability and investigate how these functional conversion agents affect the separation performance. The effects of the property differences between different conversion agents on nanochannel stabilization are demonstrated. An agent with efficient chemical reduction of GO and limited intercalation in the resulting nanochannel ensures satisfactory nanochannel stability during desalination. The stabilized membrane nanochannel exhibits a permeance of 0.69 L m⁻² h⁻¹ bar⁻¹ and excellent Na₂SO₄ rejection of 96.42%. Furthermore, this optimized membrane nanochannel demonstrates enhanced stability under varying external conditions compared to the original GO. This study provides useful information for the design of chemical conversion agents for GO nanochannel stabilization and the development of nanochannel membranes for precise separation.

• Recent Progress and Challenges in the Field of Metal–Organic Framework-Based Membranes for Gas Separation

  Shunsuke Tanaka, Kojiro Fuku, Naoki Ikenaga, Maha Sharaf, Keizo Nakagawa

  Metal–organic frameworks (MOFs) represent the largest class of materials among crystalline porous materials ever developed, and have attracted attention as core materials for separation technology. Their extremely uniform pore aperture and nearly unlimited structural and chemical characteristics have attracted great interest and promise for applying MOFs to adsorptive and membrane-based separations. This paper reviews the recent research into and development of MOF membranes for gas separation. Strategies for polycrystalline membranes and mixed-matrix membranes are discussed, with a focus on separation systems involving hydrocarbon separation, CO2 capture, and H2 purification. Challenges to and opportunities for the industrial deployment of MOF membranes are also discussed, providing guidance for the design and fabrication of future high-performance membranes. The contributions of the underlying mechanism to separation performance and adopted strategies and membrane-processing technologies for breaking the selectivity/permeability trade-off are discussed.

• Single-layer HNb3O8 with strong and nearby Lewis and Brønsted acid sites boosts amide bond hydrolysis for urease mimicking.

  Guohan Sun, Bo Yuan, Xinyu Wu, Shun Ying Lau, Linyuan Tian, Jung-Hoon Lee, Keizo Nakagawa, Yung-Kang Peng

  Urea pollution is a growing environmental concern, and its removal via catalytic hydrolysis is challenging due to the resonance-stabilized amide bonds. In nature, this reaction is catalyzed by ureases in many soil bacteria. However, the remedy of this problem with natural enzymes is not feasible as they are easily denatured and require high costs for both preparation and storage. Given this, the development of nanomaterials bearing enzyme-like activity (nanozymes) with advantages such as low production cost, simple storage, and pH/thermal stability has attracted much attention over the past decade. As inspired by the mechanism of urease-catalyzed urea hydrolysis, the co-presence of Lewis acid (LA) and Brønsted acid (BA) sites is imperative to proceed with this reaction. Herein, layered HNb3O8 samples with intrinsic BA sites were adopted for investigation. The layer reduction of this material to few-/single layers can expose Nb sites with various LA strengths depending on the degree of NbO6 distortion. Among the catalysts examined, single-layer HNb3O8 bearing strong LA and BA sites displays the best hydrolytic activity towards acetamide and urea. This sample with high thermal stability was found to outperform urease at temperatures higher than 50 °C. The acidity-activity correlation established in this study is believed to guide the future design of industrial catalysts to remediate urea pollution.

• Two-Dimensional Interlayer Space Induced Horizontal Transformation of Metal-Organic Framework Nanosheets for Highly Permeable Nanofiltration Membranes.

  Zheng Wang, Keizo Nakagawa, Kecheng Guan, Qiangqiang Song, Siyu Zhou, Shunsuke Tanaka, Yasunao Okamoto, Atsushi Matsuoka, Eiji Kamio, Guangchao Li, Molly Meng-Jung Li, Tomohisa Yoshioka, Hideto Matsuyama

  Laminar membranes comprising graphene oxide (GO) and metal-organic framework (MOF) nanosheets benefit from the regular in-plane pores of MOF nanosheets and thus can support rapid water transport. However, the restacking and agglomeration of MOF nanosheets during typical vacuum filtration disturb the stacking of GO sheets, thus deteriorating the membrane selectivity. Therefore, to fabricate highly permeable MOF nanosheets/reduced GO (rGO) membranes, a two-step method is applied. First, using a facile solvothermal method, ZnO nanoparticles are introduced into the rGO laminate to stabilize and enlarge the interlayer spacing. Subsequently, the ZnO/rGO membrane is immersed in a solution of tetrakis(4-carboxyphenyl)porphyrin (H2 TCPP) to realize in situ transformation of ZnO into Zn-TCPP in the confined interlayer space of rGO. By optimizing the transformation time and mass loading of ZnO, the obtained Zn-TCPP/rGO laminar membrane exhibits preferential orientation of Zn-TCPP, which reduces the pathway tortuosity for small molecules. As a result, the composite membrane achieves a high water permeance of 19.0 L m-2  h-1  bar-1 and high anionic dye rejection (>99% for methyl blue).

• Deformation constraints of graphene oxide nanochannels under reverse osmosis.

  Kecheng Guan, Yanan Guo, Zhan Li, Yuandong Jia, Qin Shen, Keizo Nakagawa, Tomohisa Yoshioka, Gongping Liu, Wanqin Jin, Hideto Matsuyama

  Nanochannels in laminated graphene oxide nanosheets featuring confined mass transport have attracted interest in multiple research fields. The use of nanochannels for reverse osmosis is a prospect for developing next-generation synthetic water-treatment membranes. The robustness of nanochannels under high-pressure conditions is vital for effectively separating water and ions with sub-nanometer precision. Although several strategies have been developed to address this issue, the inconsistent response of nanochannels to external conditions used in membrane processes has rarely been investigated. In this study, we develop a robust interlayer channel by balancing the associated chemistry and confinement stability to exclude salt solutes. We build a series of membrane nanochannels with similar physical dimensions but different channel functionalities and reveal their divergent deformation behaviors under different conditions. The deformation constraint effectively endows the nanochannel with rapid deformation recovery and excellent ion exclusion performance under variable pressure conditions. This study can help understand the deformation behavior of two-dimensional nanochannels in pressure-driven membrane processes and develop strategies for the corresponding deformation constraints regarding the pore wall and interior.

• Molecular dynamics study on the elucidation of polyamide membrane fouling by nonionic surfactants and disaccharides.

  Yuki Kawabata, Ralph Rolly Gonzales, Keizo Nakagawa, Takuji Shintani, Hideto Matsuyama, Yu Fujimura, Takahiro Kawakatsu, Tomohisa Yoshioka

  Reverse osmosis (RO) is a widely used energy-efficient separation technology for water treatment. Polyamide (PA) membranes are the conventional choice for this process. Fouling is a serious problem for RO separation. This issue leads to significant decreases in the water permeability of PA membranes, and it has yet to be fully elucidated. In particular, the fouling behavior of a nonionic substance on the negatively charged surface of a PA membrane in an aqueous environment has not been previously studied. In this work, the mechanisms of nonionic substances such as polyoxyethylene octyl ether (PE5) and maltose (Mal) were investigated using molecular dynamics (MD) simulations. In a PA membrane in which the carboxyl group was not dissociated, the hydrophobic portion of the membrane was exposed due to the localization of water molecules around the carboxyl groups in the PA membrane. This caused hydrophobic interaction with the hydrophobic groups of PE5. In the case of an amine-modified PA membrane containing no carboxyl groups, water was not localized around the functional group, and the water orientation of the polyamide surface was also low. Due to this membrane property, the presence of stabilized water around PE5 reduced the number of hydrophobic interactions. In similar manner, a PA membrane with a slightly dissociated carboxyl group was hydrophilic, which reduced the PE5 adsorption. The presence of many dissociated carboxyl groups, however, enhanced the adsorption of PE5 due to the increase in interactions between the dissociated carboxyl groups and the hydrophilic groups of PE5. Therefore, PE5 exhibited an amphipathic adsorption wherein both hydrophilic and hydrophobic groups contributed to adsorption onto the PA membrane. Mal, on the other hand, was highly stable in every aqueous environment independent of the state of the functional groups of the PA membrane, and was not easily affected by the properties of the PA membrane.

• Gas Permeation Characteristics of TiO₂-ZrO₂-Aromatic Organic Chelating Ligand (aOCL) Composite Membranes

  Takashi Tachibana, Tomohisa Yoshioka, Keizo Nakagawa, Takuji Shintani, Eiji Kamio, Hideto Matsuyama

  Methyl gallate (MG) and ethyl ferulate (EF) with a benzene ring were separately used as aromatic organic chelating ligands (aOCLs) to prepare two versions of TiO2-ZrO2-aOCL composite sols via hydrolysis and polycondensation reactions with titanium(IV) isopropoxide (Ti(OC3H7)4) and zirconium(IV) butoxide (Zr(OC4H9)4). Thermogravimetric and FT-IR analysis of dry gels revealed that aromatic rings were present in the residual organic matter when the gel was fired under nitrogen at 300 °C. In X-ray diffraction (XRD) measurements, the TiO2-ZrO2 composite material prepared using these two aOCLs showed an amorphous structure with no crystalline peaks for TiO2 and ZrO2. In N2 adsorption/desorption measurements at 77 K, the TiO2-ZrO2 samples using the aOCLs as a template appeared porous with a larger specific surface area than TiO2-ZrO2 without aOCL. TiO2-ZrO2-aOCL composite membranes were prepared by coating and firing TiO2-ZrO2-aOCL sol onto a SiO2 intermediate layer using an α-alumina porous tube as a substrate. Compared with the TiO2-ZrO2 membrane, the TiO2-ZrO2-aOCL membranes had higher gas permselectivity. The TiO2-ZrO2-EF membrane showed a He permeance of 2.69 × 10-6 mol m-2 s-1 Pa-1 with permeance ratios of He/N2 = 10.6 and He/CF4 = 163, while the TiO2-ZrO2-MG membrane revealed a bit less He permeance at 8.56 × 10-7 mol m-2 s-1 Pa-1 with greater permeance ratios of He/N2 = 61.7 and He/CF4 = 209 at 200 °C. A microporous TiO2-ZrO2 amorphous structure was obtained by introducing aOCL. The differences in the side chains of each aOCL could possibly account for the differences in the microporous structures of the resultant TiO2-ZrO2-aOCL membranes.

• Influence of Photocatalysis on Blood Cell Attachment over Protein-Immobilized Polystyrene Surfaces Modified with a Poly(styrene)-b-Poly(acrylic acid) Copolymer.

  Chih-Chen Yeh, Keizo Nakagawa, Yung Chang, Chechia Hu

  In the present study, thrombocytes, erythrocytes, and leukocytes were individually brought into contact with different immobilized blood proteins on the surface of polystyrene (PS), which was modified with a poly(styrene)-b-poly(acrylic acid) copolymer. When the concentration of fibronectin was greater than 5 μg mL-1, the attachment of erythrocytes increased, which indicated that the modified PS surface was less compatible with erythrocytes. In addition, vitronectin and laminin attached on the surface increased the adhesion of thrombocytes; higher adhesion was observed for leukocytes in the cases of fibrinogen, lysozyme, and laminin. Interestingly, adhesion properties of blood cells on the protein surface could be influenced by the addition of metal oxide- and carbon-based photocatalysts. After a photocatalytic treatment by metal oxide-based TiO2, the adhesion amounts of erythrocytes improved slightly, whereas the adhesion of leukocytes and thrombocytes decreased after treatment with a carbon-based g-C3N4 nanosheet. Our results suggested that the surface modification of the substrate through photocatalysis using various photocatalysts along with the grafting of the poly(styrene)-b-poly(acrylic acid) copolymer could be a promising approach to alternatively control the blood compatibility on the protein surface.

• REMOVAL OF AQUEOUS AMMONIUM FROM SEAWATER AND FRESHWATER USING MAGNESIUM HYDROGEN PHOSPHATE

  Shigeru Sugiyama, Tomoki Hayashi, Dai Ioka, Keizo Nakagawa, Ken-Ichiro Sotowa

  Aqueous ammonium is a threat to the vitality of various fish and the present study examined the feasibility of its removal from both seawater and freshwater using magnesium hydrogen phosphate (MgHPO₄). Regardless of the type of water, aqueous ammonium was favorably removed particularly under basic conditions such as a pH = 10. Even under neutral conditions (pH = 7), some aqueous ammonium can be removed. The results of the present study showed that MgHPO₄ can be used to remove a serious threat to the vitality of fish posed by the dilute concentration of aqueous ammonium in both seawater and freshwater. The resultant formation of magnesium ammonium phosphate (MAP) was detected by X-ray diffraction (XRD), which confirmed the removal of aqueous ammonium. It is common knowledge that MAP is a fertilizer for waterweeds, which are essential for the growth of the fish while simultaneously promoting their nourishment.

• RECOVERY OF PHOSPHATE FROM UNUSED RESOURCES

  The recovery of aqueous phosphate from a model solution consisting of NH₄⁺, NO₂^- and NO₃^-, which are contained in a surplus that phosphate in rivers in Tokushima Prefecture, Japan, using boehmite together with the elution behaviors of phosphate from dephosphorization slag using various eluates were examined. The recovery of aqueous phosphate using boehmite was not influenced by the coexistence of those nitrogen-containing contaminants under various pH conditions. For the elution behaviors of phosphate from dephosphorization slag, it was found that aqueous HNO₃ among various acidic and basic solutions was a suitable solution as an eluate. Present study suggests that the employment of the unused resources such as aqueous phosphate in rivers and phosphate in the dephosphorization slag can be used as a possible candidate as a new raw material for rare phosphate.

• NF/RO Separation of Organic Solvent using Organic and Inorganic Membranes

  Shintani Takuji, Nakagawa Keizo, Yoshioka Tomohisa, Matsuyama Hideto

  Separation of organic solvent by membrane is an emerging technology for the purification or separation of organic solvents. In this study, game changing OHF (Organic solvent Hyper Filtration) membranes and their applications are under development to realize the replacement from energy–consuming distillation to energy–efficient membrane process. Nano filtration (NF)–type hollow fiber OHF membrane was developed by TIPS (Thermally–Induced Phase Separation) method using solvent–resistant polymers such as nylon 6. The prepared membranes showed methanol (MeOH) permeability of > 2 LMH (L･m–2･h–1) with molecular weight cut–off (MWCO) of about 1,000 and stability for >1 month. Reverse osmosis (RO)–type organic composite OHF membrane was developed by the interfacial polymerization method. A highly cross-linked polyamide layer was prepared on a solvent resistant support membrane. The membrane showed selectivity for MeOH against toluene (TOL) in separation test using MeOH/TOL mixture. Membrane performance was Rej.＝ 65% Flux ＝ 16 LMH at 40 bar. The stability was > 2 weeks. NF–type TiO2/ZrO2 ceramic composite OHF membrane was developed using organic chelating ligands (OCL) as a pore size–fixing spacer. The membrane showed high permeability for organic solvents such as hexane (26 LMH) and MeOH (25 LMH) at 6 bar with MWCO of about 1,000 and stability of > 1 week. NF–type inorganic nanosheet OHF membrane was developed by laminating nanosheets of niobate and/or graphene oxide onto solvent resistant support membrane using chemical binders. The membrane showed relatively high MeOH permeability (11 LMH at 2 bar) and good rejection against organic dyes such as Evans blue (Mw : 960.8) with 87%.

• Development of metal oxide nanosheet membranes: separation performance in water and organic solvent

  Nakagawa Keizo

  Two dimensional (2D) nanosheet membranes have opened up a new avenue for fabricating size-selective molecular separation membranes, benefiting from their unique atomic thickness with micrometer lateral dimensions. Stacked nanosheet membranes are formed by assembling single molecular sheets into thin membranes, and contain 2D nanochannels between the stacked sheets that allow water or solvents to pass through whilst rejecting unwanted solutes. Therefore, they represent promising materials for potentially high-functional membranes for liquid separation such as water treatment and organic solvent filtration. In this study, we fabricated nanosheet membranes using single 2D nanosheets of metal oxide such as niobate nanosheets. The channel structure and application for water treatment and organic solvent filtration will be discussed.

• The oxidative dehydrogenation of methane, ethane, propane and isobutane on FSM-16 doped with chromium

  FSM-16にクロムを導入した触媒は、イソブタンの酸化脱水素反応によるイソブテンの接触反応に高活性を示し、高活性酸化脱水素触媒であるマグネシウムバナデート等より優れた性能を示した。一方、この触媒を、メタンの酸化カップリング、エタンおよびプロパンの酸化脱水素反応に適応しても、高い触媒活性は得られなかった。本触媒系は直鎖炭化水素の酸化脱水素には有効でなく枝分かれした炭化水素に高い活性を示すことがわかった。

• International Collaborative Research for Development of Silica-coated Pd Catalysts : Sintering Resistance and Catalytic Property for CyclohexaneDdehydrogenation in Bach Reactor

  Nakagawa Keizo, Hoshinoo Tomoya, Sotowa Ken-Ichiro, Sugiyama Shigeru, Rkiouak Laylla, Dubois Vincent, Hermans Sophie

  Here we developed silica-coated Pd catalysts and applied to liquid phase catalytic reaction such as dehydrogenation of cyclohexane. Carbon black (CB)-supported Pd catalysts (Pd/CB) were covered with organosilica layers via the hydrolysis of phenyltriethoxysilane (PhTES). Coverage of Pd nanoparticles with organosilica layers suppressed particle sintering of Pd, as compared to the case of uncovered Pd/CB. The organosilica layers had hydrophobic properties because of the presence of phenyl groups. As a result, the organosilica-coated Pd catalysts prepared using PhTES showed superior catalytic performance for cyclohexane dehydrogenation, even after reduction at 623K under H2 atmosphere.

• Preparation of Metal Nanoparticles Covered with Functionalized Silica Layers and Application to Catalyst Materials

  NAKAGAWA Keizo

  The coverage of metal particles with silica layers is an effective method to functionalize the surface of metal particles. One of the advantages of the coverage of silica layers is to enhance the stability of metal particles. Silica-coated metal nanoparticles can be applied to various catalytic reactions through the fine structure of silica layers. The development of functionalized silica layers which cover the metal particles would lead to an increase in their application for catalytic reactions. This report will describe the preparation process of silica-coated metal particles using several organosilanes and application to the catalytic reaction involving larger reactant molecules. Pt particles covered with functionalized silica layers have sintering resistance to thermal treatment and show superior catalytic activity for dehydrogenation of organic hydride.

• Propylene preparation from high concentration of ethanol on Ni-doped FSM-16

  Sugiyama Shigeru, Toyoda Saeko, Ogawa Shiro, Nakagawa Keizo, Sotowa Ken-Ichiro

  It is generally accepted that the conversion of ethanol to propylene favorably proceeds on Ni-doped FSM-16 together with Ni-doped MCM-41. However most of the studies on the conversion have been examined at a low concentration of ethanol by 1 kPa and the examination at a higher concentration of ethanol is needed for the purpose of practical use of the conversion. In the present study, a higher concentration of ethanol by 30 kPa is used for the conversion to reveal some problems under the reaction conditions.

• Preparation of Carbon-Supported Pt Catalysts Covered with Silica Layers and Application to Dehydrogenation Catalysts of Organic Hydride

  Nakagawa Keizo, Tanimoto Yusuke, Sotowa Ken-Ichiro, Sugiyama Shigeru

  Carbon-supported Pt metal nanoparticles covered with silica layer including phenyl or methyl groups were prepared using successive hydrolysis of 3-aminopropyl-triethoxysilane (APTES) and phenyltriethoxysilane (PhTES) or methyltriethoxysilane (MTES). The Pt catalyst covered with silica layers containing functional groups showed higher activity in the cyclohexane dehydrogenation, compared with Pt catalysts covered with a silica layer containing no functional groups, because the microporous structure of silica layers which wrapped Pt metal particles increased the diffusion capability of cyclohexane. The Pt/CB nanoparticles covered with microporous silica layers showed the high sintering resistance of Pt metal particles to thermal treatment at 973 K in a H2 atmosphere as compared with Pt/CB. As a result, this catalyst showed higher catalytic activity for cyclohexane dehydrogenation than Pt/CB after thermal treatment.

  化学品製造プロセスにおいて有機溶剤の分離・濃縮に多用される蒸留法は、多量の熱エネルギーを必要とする極めてエネルギー消費の大きいプロセスである。本研究では、大幅な省エネルギー化を目指して、直接溶剤－溶剤間の膜分離を行う新規有機溶剤超ろ過膜法（Organic solvent Hyper Filtration; OHF）の創出を行う。OHF膜法では有機溶剤を液体のまま膜を透過させるため、圧倒的な省エネルギーが達成可能であり、蒸留法と比較して、所要エネルギーを1/100以下に削減が可能である。現在、分離緻密層として、新設計の界面重合ポリアミド中に二硫化モリブデン（MoS2）ナノシートを配向させることで溶剤の選択透過性と膜強度の両立を実現させた複合膜の作製を進めている。MoS2ナノシートは層間隔を架橋剤で精密に制御することで有機溶剤の選択透過パスとして用いることができ、分子ふるい効果による有機溶剤の選択分離が可能である。溶剤－溶剤分離を可能にするOHF膜はこれまで世の中に無く、これを創製することで、蒸留法を用いる旧来の化学プロセスを未来型の革新的化学プロセスに変革が可能になると期待される。

  Inorganic membranes have excellent chemical resistance and mechanical strength. Therefore, the inorganic membranes have a wide range of applications, a long membrane life, and relatively high separation property. However, there are problems in terms of permeance, membrane-forming, and manufacturing cost. In this study, we have developed ultrathin laminar membranes using graphene oxide and niobate nanosheets for water treatment. The composite membranes showed higher separation properties of salts than each single laminar membrane. From the results of structural analysis such as the positron annihilation method and molecular dynamics simulation, it was clarified that high separation performance is exhibited by the formation of an interfacial dense heterolayer between different nanosheet layers.

  The forward osmosis (FO) membrane process is an ultimate energy-saving membrane separation water treatment method that utilizes the phenomenon of spontaneous water movement through osmotic pressure difference. In this study, we created an original, innovative, and highly water-permeable water channel substance specialized for forward osmosis process, created a channel-type FO membrane incorporating the water channel substance, and created a novel ionic liquid-type draw solution (DS) that is temperature-responsive and can be recovered and regenerated by thermal phase separation. We also developed a water treatment process using these membrane and DS, and achieved a significantly energy-saving seawater desalination process that consumes less energy than the conventional reverse osmosis membrane method.

  Porous inorganic membranes have advantages of high temperature resistance, chemical stability and mechanical strength, therefore, various researches for water treatment have been investigated. In this study, stacked nanosheet membranes utilizing two-dimensional nanosheets were fabricated for the development of functional inorganic membranes with superior water permeability, separation performance as well as high antifouling property. We have successfully fabricated the stacked nanosheet membranes with high structural stability using simple vacuum filtration method. The nanosheet membranes show high rejection against anionic organic dyes and divalent salts, which were found to act as nanofiltration. Furthermore, the fouling resistance with recovery function of water flux under ultraviolet light irradiation was also confirmed.

• New approach of preparation of thin and durable Pd membrane by introduction of double silica layers into porous SUS support

  Katoh Masahiro, NAKAGAWA Keizo

  Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), Grant-in-Aid for Scientific Research (C), The University of Tokushima, 01 Apr. 2013 - 31 Mar. 2016

  In this study, thin and durable palladium (Pd) membranes were prepared by a new approach. Double intermediate layers were introduced into porous stainless steel (PSS) supports. The purposes were to modify the pore size of the PSS support and to improve the hydrogen permeability. At first, silicalite with micro pores and mesoporous silica (MCM-48) were selected as double layers. But the mechanical strength of these layers were not enough for electro-less plating of Pd on layers. For an enhancement of durability of intermediate layers, an alumina (boehmite) layer with mesopores was choose as an upper intermediate layer. As the results, Pd membrane with mesoporous silica showed high hydrogen permeance and Pd membrane with silicalite showed no helium permeance at room temperature. The results of this research show that the introduction of double intermediate layers into porous stainless steel support was effective for controlling both hydrogen permeance and selectivity.


• Development of layered nanosheet photocatalysts using lamellar phase as a template and their catalytic properties

  Two dimensional transition metal oxide sheets are expected to be utilized in various scientific fields because of their attractive features such as high surface areas and unique surface properties. However, improvements in the preparation method and application for the photocatalysts should be necessary. In this study, nanosheet composite photocatalysts are prepared toward the development of high functional photocatalysts. Single molecular sheets of niobate are successfully prepared by a simple bottom-up approach and show superior photocatalytic activity for hydrogen evolution from water under UV light irradiation. Photocatalytic hydrogen evolution activity is much enhanced over composite of single niobate sheets with other materials such as graphene and MoS2 due to efficient electron transfer and charge separation.

  In the catalytic liquid-phase oxidation, dissolution of gaseous oxygen may be the rate determining step. In the present study, the heterogeneous and homogeneous catalytic oxidations in a liquid phase wers examined using a micro reactor, in which the slug flow can be easily formed. The slug flow has an advantageous property, in which the rate of the dissolution of gaseous oxygen is enhanced. As an example obtained in the present study, in the oxidation of ethyl lactate to the ethyl pyruvate using VOCl3, that is, homogeneous catalytic system, the yield of ethyl pyruvate was enhanced by 8% on using the microreactor. In the palladium catalyst system for the liquid phase oxidation, the doping of the palladium catalyst with heavy metals is sometimes needed due to a lack of oxygen in the liquid. However, the results obtained in the present reaction indicates that doping of palladium catalyst with heavy metal is not needed in using the micro reactor.

  自己組織化プロセスによるラメラ相鋳型法により開発した層状ナノシート光触媒を含むゲルを利用してチタニア電極を作製し、色素増感太陽電池への応用を行った。ナノシート層間に新しい物質粒子層の積層ナノシート構造を形成させ、層状構造の耐久性を向上させることに成功した。しかし、有機色素の光分解実験においては活性が得られ無い等の電極として実用するための今後の研究課題も見つかった。一方、色素増感太陽電池の検討では層状ナノシートのみでは効果的な結果が得られなかったものの、P-25と層状ナノシートを混合したゲルを用いて作製した電極では、重量比を変化させた際にP-25標準電極を上回る変換効率が得られた。今後低温焼成による電極作製法の確立等によりさらなる効率の改善が期待できる。

  The coverage of metal catalysts with silica layers is an effective method to enhance the stability of catalysts. On the other hand, it brings about the possibility of decrease of activity because the silica coverage could suppress diffusion rate of reactant. In addition, the application could be confined to catalytic reaction associated with small molecules. In this study, we prepared metal catalysts covered with porous and thin silica layers. It was found that the silica-coated metal catalysts had remarkable thermal stability of the metal without major sintering and showed high catalytic activity because the microporous and thin silica layers enable the high diffusion rate.

  Phosphorus is an important element for various advanced materials. However it is pointed out that phosphorus ore, that is a main raw material of phosphorus, will disappear in the near future. Therefore a new system, that is not dependent on phosphorus ore, should be established as early as possible. In order to reply to the serious problem, researchers in the field of engineering, pharmacy and dentistry in the University of Tokushima have extensively studied the followings in the present project : (1) Search of new phosphorus sources and development of the qualitative and quantitative detection technique of various phosphorus-containing compounds. (2) Development of new process for the recovery of aqueous phosphorus-containing compounds. (3) Development of advanced functions of phosphorus-containing compounds. (4) Application of advanced functions of phosphorus-containing compounds.

Cerium carbonate with nanowires, nanorods, nanosheets morphology has been successfully synthesized using surfactants. Their morphologies were sustained after thermal decomposition-oxidation to ceria. Each ceria nanoparticles synthesized using surfactant exhibited higher oxygen storage capacity than ceria nanoparticles synthesized without surfactants. These ceria nanoparticles showed superior activity for the carbon combustion than JRC-CEO-1.

  地球環境問題とエネルギーの安定供給に対する対策として水素利用技術の期待が高まる中,有機ハイドライドの脱水素反応を利用した水素貯蔵・供給システムが注目されている。この反応は吸熱反応であるため高温での反応が有利となるが、高温反応下では触媒担体上の貴金属粒子がシンタリングし、活性低下が起こるため、触媒の長寿命化が望まれている。本研究課題では、シリカ被覆Pt触媒を用いて有機ハイドライド脱水素反応を行い、高温反応下におけるシンタリング耐性に優れた触媒の研究開発を行う。

  PEFC電極触媒について、アノード電極ではPtのCOによる被毒が、カソード電極ではPtの溶出が問題となっている、本研究ではこれらの問題に対応可能なPt電極触媒を最終目標として、シリカ被覆Ptナノ粒子を用いた電極触媒の研究開発を行った。以下に得られた結果について示す。 1シリカ被覆PtをPEFCのアノード電極に用いた場合、シリカ層によるH_2とCOの分離により、COを100ppm含む水素を供給した場合でCO被毒耐性が得られた。またシリカ被覆PtにCoを添加し700℃でエチレン分解を行うことでカーボンナノチューブ(CNT)を生成させた場合、高い発電特性が得られたが、一方CO被毒耐性が低下した。シリカ内部のPt上で水素が活性化され、生成した電子がCNTにより効率よく移動したため発電特性は向上するが、CNT生成に伴いシリカの細孔構造が崩れたためCO被毒耐性を保つには至らなかったと考えられる。CO被毒耐性については、今後シリカ被覆Pt触媒の電子伝導性の向上に対する別のアプローチが必要であると考える。 2カーボンナノチューブを生成したシリカ被覆Pt触媒をカソード電極に用いて、電位変動によるPt溶出耐久試験を行った。炭素担持Pt触媒では500回のサイクルで発電特性が半減したものの、シリカ被覆Pt触媒ではPtのシンタリングを抑制させることができ、発電特性が保たれるという結果が得られ、高い溶出耐性が示された。このようにPt溶出耐性について、シリカ被覆Pt触媒が有効であるという重要な知見が得られた。
