炭素触媒、電池電極及び電池
Document Type and Number:
Japanese Patent JP7077275
Kind Code:
B2
Abstract:
Provided are a carbon catalyst, a battery electrode, and a battery, each having excellent catalytic activity and excellent durability. The carbon catalyst has a carbon structure that has a crystallite size Lc falling within a range of 0.90 nm or more and 1.20 nm or less calculated through use of a Bragg angle of a diffraction peak fbroadat a diffraction angle 2θ of 24.0°±4.0° obtained by separating a diffraction peak in the vicinity of a diffraction angle 2θ of 26° in an X-ray diffraction pattern obtained by powder X-ray diffraction using a CuKα ray, and that exhibits a carbon dioxide desorption amount in the temperature range from 650°C to 1,200°C of 97 µmol/g or less, a total of a carbon monoxide desorption amount and a carbon dioxide desorption amount in the temperature range from 650°C to 1,200°C of 647 µmol/g or less, or a carbon monoxide desorption amount in the temperature range from 650°C to 1,200°C of 549 µmol/g or less in a temperature programmed desorption method including measuring a carbon dioxide desorption amount in the temperature range from 25°C to 1,200°C.
