▎ 摘　　要

NOVELTY - Graphene oxide dopeded with cobalt disulfide preparation involves dissolving graphene oxide in a solvent for preparing graphene oxide solution. The prepared graphene oxide solution is mixed with metal precursor and organic minerals for carrying out hydrothermal synthesis. The hydrothermally synthesized product is cooled at room temperature and then washed and dried to obtain hybrid graphene oxide in which cobalt disulfide or nanoparticles are dispersed to give the finished graphene oxide dopeded with cobalt disulfide. USE - Method for preparing graphene oxide dopeded with cobalt disulfide. ADVANTAGE - The method prepares the graphene oxide dopeded with cobalt disulfide in a simple and cost-effective manner with excellent activity in hydrogen generating reaction as electro-catalyst and high catalyst stability for a long time. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene oxide dopeded with cobalt disulfide preparation method.
