▎ 摘　　要

NOVELTY - Manufacture of cobalt-loaded porous carbon composite graphene electrocatalyst involves mixing and stirring a cobalt salt, a carbon source and deionized water, adding graphene oxide, ultrasonically treating to obtain a mixed solution, transferring the mixed solution to a reactor, heating, reacting, cooling to room temperature, centrifuging, washing, drying to obtain cobalt-loaded graphene/carbon material, mixing obtained material, nitrogen-containing organic substance and an organic solvent, heating, cooling to room temperature, removing the solvent, drying, heating and calcining under inert gas protection, and cooling to room temperature. USE - Manufacture of cobalt-loaded porous carbon composite graphene electrocatalyst for zinc-air battery. ADVANTAGE - The cobalt-loaded porous carbon composite graphene electrocatalyst having excellent catalytic performance can be produced economically by simple method, and provides battery having improved open circuit voltage.
