▎ 摘  要

NOVELTY - Preparation of cobalt disulfide/sulfur nitrogen co-doped graphene catalytic material involves (S1) ultrasonically dispersing 10-20 mg/mL graphene oxide in deionized water, adding 20-30 mg/mL organic dispersant morpholino ethanesulfonic acid to obtain a mixed dispersion, adding and mixing cobalt metal salt and sulfur powder in a molar ratio of 1:5 to obtain a mixed liquid, (S2) hydrothermally reacting the mixed liquid at 150-180 degrees C in a hydrothermal reactor, cooling to room temperature, washing the solid product, drying to obtain a precursor solid powder, (S3) heating the precursor solid powder to 300-600 degrees C for calcination in nitrogen atmosphere, and reducing the temperature. USE - Preparation of cobalt disulfide/sulfur nitrogen co-doped graphene catalytic material used in fuel cell (all claimed). ADVANTAGE - The process is simple, and provides catalytic material which has stable structure, excellent electroconductivity, excellent catalytic performance and high stability.
