Patent ID: 11344867

Abstract:
A carbon catalyst has: a carbon structure that exhibits a nitrogen desorption temperature range from 800° C.-1,000° C. of 0.75×10−5 mol/g or more or a nitrogen desorption amount in the range from 600° C. to 1,000° C. of 1.20×10−5 mol/g or more in a temperature programmed desorption method including measuring nitrogen desorption amount temperature range from 600° C.-1,000° C.; a carbon structure exhibits a zeta potential isoelectric point of pH 9.2 or more; or a carbon structure exhibits a ratio of an intensity of a first nitrogen peak within a range of a binding energy of 398.0±1.0 eV, to an intensity of a second nitrogen peak having a peak top within a range of a binding energy of 400.5±1.0 eV, of 0.620 or more, the first and second nitrogen peaks obtained by separating a peak derived from a 1s orbital of a nitrogen atom in a photoelectron spectrum obtained by X-ray photoelectron spectroscopy.
