高機能性多孔性炭素材の創成と応用
Development of high-performance porous carbon materials for energy saving and environmental protection

研究の背景 Background

物質の貯蔵・分離に欠く事ができない多孔性炭素材の機能は、表面及び細孔構造に大きく依存しています。細孔発達のメカニズムを解明することで表面及び細孔構造をより精密に制御することが可能となり、そしてエネルギーや環境分野などの用途に合わせた高機能・新機能を有する多孔性炭素材を創製できるようになります。

Functions of porous carbon materials, which are indispensable for material storage and separation, strongly depend on surface and pore structures. Understanding of pore development mechanism enables to finely control the surface and pore structures of the porous carbon materials, and then a fabrication of the porous carbon materials having high and new functionalities optimized for applications of energy saving and environmental protection fields becomes possible.

研究の目標 Outcome

エネルギー及び環境問題の解決に貢献できる高性能多孔性炭素材の開発を目指しています。機能発現の鍵である細孔構造発達メカニズムを解明し、それに基づいた材料開発、吸着式ヒートポンプや大気浄化などの応用特性評価を行っています。

Research is aimed at a development of high-performance porous carbon materials to solve energy and environmental problems. Mechanism of pore development is tried to be elucidated, and new porous carbon materials are being fabricated based on the hypothesis. Applications of the newly prepared porous carbon materials to various purposes, such as adsorption heat pump and air purification, are also investigated
