▎ 摘 要
NOVELTY - Preparation of cobalt-doped mesoporous carbon/graphene composite material involves taking mesoporous carbon and graphene oxide, adding salt solution, mixing, freeze-drying to obtain dry mixture, and performing heat treatment under ammonia gas using tubular furnace at 800-1000 degrees C for 20-80 minutes. USE - Method for preparing cobalt-doped mesoporous carbon/graphene composite material (claimed) used in capacitor, lithium ion battery, organic catalysis or light catalysis. ADVANTAGE - The method has simple preparation and excellent electric catalytic reduction property.
