有機化合物を用いたガス貯蔵材料の開発
有機化合物と金属イオンが結合した多孔質高分子（PCP: Porous Coordinated Polymer）についてガス吸着能力や表面積及び化学構造の観察など多角的に調査を行っている。新規な2種類のPCPを合成し，それらの水素貯蔵能力，二酸化炭素吸着能力，吸着メカニズム，熱的挙動及び表面形態の観察結果について報告する。多くのPCP構造の中から仕様を選択したPCPについてメタンの吸着現象に関する知見について述べる。

Gas Absorption and Adsorption Methodology Utilizing Organic Compounds
We are conducting a multifaceted investigation into porous coordinated polymers (PCP), which are formed by the combination of organic compounds and metal ions, focusing mainly on their gas adsorption capabilities, surface area, and chemical structure observation. This paper reports on the synthesis of two novel types of PCP and their hydrogen storage capacity, carbon dioxide adsorption capacity, adsorption mechanisms, thermal behavior, and surface morphology observation results. This study also discusses insights into the methane adsorption phenomena concerning PCPs selected from various PCP structures based on a criterion.
