CARBON MATERIAL FOR CATALYST SUPPORT USE

摘要

A carbon material for catalyst support use which, when used as a catalyst support, maintains a high porosity while being stable chemically, having electrical conductivity, being excellent in durability, and being excellent in diffusibility of the reaction starting materials and reaction products is provided. It is characterized by comprising dendritic carbon mesoporous structures which have 3D structures of branched carbon-containing rod shapes or carbon-containing ring shapes, having a pore size of 1 to 20 nm and a cumulative pore volume of 0.2 to 1.5 cc/g found by analyzing a nitrogen adsorption isotherm by the Dollimore-Heal method, and having a powder X-ray diffraction spectrum which has a peak corresponding to a 002 diffraction line of graphite between diffraction angles (2θ: degrees) of 20 to 30 degrees and has a peak with a half value width of 0.1 degree to 1.0 degree at 25.5 to 26.5 degrees.
