Title CARBON-BASED MATERIAL, ELECTRODE CATALYST, OXYGEN REDUCTION ELECTRODE CATALYST, GAS DIFFUSION ELECTRODE, AQUEOUS SOLUTION ELECTROLYTIC DEVICE, AND PRODUCTION METHOD FOR CARBON-BASED MATERIAL
Abstract

Provided is a carbon-based material having high catalytic activity. This carbon-based material comprises a graphene doped with a metal atom and at least one type of non-metallic atom selected from a nitrogen atom, a boron atom, a sulfur atom, and a phosphorous atom. The ratio, for the carbon-based material, between the maximum peak intensity derived from an inactive metal compound and a metal crystal, and the (002) surface peak intensity in a rocking curve obtained by x-ray diffraction measurement using a CuKalpha ray is no more than 0.1.
