NOVELTY - Manufacture of manganese-cobalt/graphene composite nanomaterial involves adding predetermined amount of deionized water to graphene oxide, ultrasonically dispersing, adding potassium permanganate solution of predetermined concentration at constant rate under light condition, adding a cobalt salt, reacting, filtering, washing with deionized water, lyophilizing, grinding to obtain manganese-cobalt/graphene composite, adding deionized water and glucose solution, magnetically stirring, adding ammonia, stirring at preset temperature, cooling to room temperature, filtering, washing and drying. USE - Manufacture of manganese-cobalt/graphene composite nanomaterial (claimed). ADVANTAGE - The manganese-cobalt/graphene composite nanomaterial is produced by simple method without affecting the environment.
