Outline of Final Research Achievements |
Carbon-based membranes are in the limelight as novel and high-performance materials for various applications. This study focuses on the fabrication of carbon-based membranes via a hydrothermal method from aqueous glucose solutions. We have optimized the operating time and temperature for the hydrothermal treatment by evaluating the surface microstructure of the as-prepared membranes using various techniques. The elemental constitution of the membrane was investigated, and its bonding state using characterization techniques. The result of the gas transmission rate measurement indicates that the pore size of the obtained carbon membrane is around 0.3 nm. The obtaned membranes show appropriate pore sizes to act as molecular sieves for the purification of hydrogen gas.

Academic Significance and Societal Importance of the Research Achievements |
現在のカーボン膜は、ポリマー膜の炭化法や蒸着法など、限られた方法のみで作製されており、性能の向上とともに簡便な製造方法の開発が望まれている。本研究で構築した水熱処理法による作製方法は、これまでのカーボン膜の作製方法とは異なり、簡便に複雑形状の担体への成膜が可能な技術であることから、来る水素社会へ貢献が期待される技術である。また、水熱法の条件を詳細に検討できたことから、今後カーボン膜を作製する際の学術データベースとしての役割も期待される。
