▎ 摘 要
NOVELTY - Heterostructured samarium cobalt oxide-decorated reduced graphene oxide is prepared by preparing graphene oxide, preparing homogeneous solution by mixing samarium (III) nitrate, cobalt nitrate hexahydrate and urea3, and dispersing the mixture in samarium coke oxide. The homogeneous graphene oxide solution is maintained in an autoclave. The heterostructure of samarium-cobalt oxide is evaluated by characterizing the graphene oxide. USE - The heterostructure is useful for manufacturing hybrid supercapacitor device. ADVANTAGE - The samarium cobalt oxide-decorated reduced graphene oxide has excellent electrochemical performance.
