NOVELTY - Preparing graphene oxide/metal-organic framework (MOF) derived porous cobalt oxide/graphene material involves adding potassium cyanocobaltate solution into the graphene oxide solution, ultrasonically mixing, then adding cobalt chloride solution to obtain the reaction liquid, carrying out in-situ polymerization reaction to the reaction liquid to obtain the precursor of the composite material, and orderly centrifuging the composite material precursor, drying and calcining to obtain the target product. USE - The method used for preparing graphene oxide/metal organic framework derived porous cobalt oxide/graphene material, which is useful in supercapacitor. ADVANTAGE - The method is environment-friendly, simple and easy to operate, convenient for industrial production, and has wide application prospect in the field of super capacitor.
