摘要： A carbon material for catalyst support includes elongated carbon mesoporous structures containing graphene. The carbon mesoporous structures each have a major axis in a range of 50 nm to 200 nm and a minor axis in a range of 30 nm to 100 nm. Pore diameters and a cumulative pore volume determined through analysis of a nitrogen adsorption isotherm using a Dollimore-Heal method are respectively in a range of 1 nm to 20 nm and in a range of 1.5 cc/g to 2.5 cc/g.

摘要： Disclosed is a method of producing a catalyst. The method includes: dispersing, in an acid solution, a composite in which a plurality of raw material microparticles containing a noble metal is supported on a carbon support doped with a nitrogen atom and a first transition metal atom; immersing a noble metal member in the acid solution; and alternately blowing a first gas containing an oxidizing gas and a second gas containing a reducing gas into the acid solution.
