NOVELTY - Method for manufacturing transition metal oxide/graphene composite, involves mixing transition metal precursor aqueous solution and graphene aqueous dispersion, and reducing the transition metal precursor by heat-treating the obtained mixture. USE - The method is useful for manufacturing transition metal oxide/graphene composite which is used in secondary battery, fuel cell, supercapacitor and gas sensor (all claimed). ADVANTAGE - The transition metal oxide/graphene composite has high specific area, and can be prepared without using reducing agent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for transition metal oxide/graphene composite, which is manufactured by the above-mentioned method.
