炭素材料の多孔質化・添加金属による機能付与に関する研究

抄録

The addition of metals to carbon materials gives it properties that are not possessed by the carbon material itself. One typical form of such an inclusion is a single metal atom with four nitrogen atoms in square planar configuration (metal-N₄ site) embedded in the π-conjugated plane, which serves as an active center of a heterogeneous catalyst. A critical factor in achieving a high activity in such a heterogeneous catalysts is the development of pores to sufficiently expose the active sites to the surface and the effective transport of reactants and products. This review describes carbon materials with the metal-N₄ site and the developed pores, which are used in energy conversion and storage devices, such as fuel cells, water electrolyzers, and redox flow batteries. The carbon materials formed by the author as a result of an original and innovative selection of the proper raw materials and synthesis procedures are demonstrated.
