炭素系材料、電極触媒、酸素還元電極触媒、ガス拡散電極、水溶液電解装置、並びに炭素系材料の製造方法

摘要

The present invention provides a carbon-based material with high catalytic activity. The carbon-based material in accordance with the present invention includes graphene doped with metal atoms and at least one type of non-metal atoms selected from a group consisting of nitrogen atoms, boron atoms, sulfur atoms, and phosphorus atoms. A diffraction pattern obtained by X-ray diffraction measurement of the carbon-based material by use of CuK± radiation shows that a proportion of the highest of intensities of peaks derived from an inactive metal compound and a metal crystal to an intensity of a (002) peak is 0.1 or less.
