▎ 摘　　要

NOVELTY - A nickel-cobalt oxide/graphene nano-hybrid material is prepared by complexing nickel salt, cobalt salt, imidazole-based ligand, and graphene in a solvent, performing solid-liquid separation to obtain a solid phase product. The solid phase product is added to a solvent containing nickel salt and cobalt salt for solvothermal treatment to obtain a zeolite imidazole ester/graphene composite. The zeolite imidazole ester/graphene composite is calcined under a protective atmosphere at 300-900 degrees C to obtain the finished product. USE - Nickel-cobalt oxide/graphene nano-hybrid material for use in electro-chemical sensor for detecting hydrogen peroxide (all claimed). ADVANTAGE - The nickel-cobalt oxide/graphene nano-hybrid material has specific surface area and immanent hollow structure, and is capable of providing rich active sites for catalytic reaction, such that it has a high catalytic activity.
