摘要

The carbon-based material according to the present invention is doped with a nonmetallic atom such as a nitrogen atom and a metal atom. Further, in the radial distribution function obtained by Fourier transform of the K-edge EXAFS of the metal atom, the vicinity of the coordinate bond distance between the metal atom and the nonmetal atom with respect to the intensity B of the maximum peak appearing near the metal bond distance of the metal atom The ratio A / B of the intensity A of the maximum peak appearing in is 4.0 or more. However, when the metal atom is a platinum atom, the ratio A / B in the radial distribution function obtained by Fourier transforming the LIII end EXAFS of the platinum atom is 4.0 or more.
