▎ 摘  要

NOVELTY - Making a metal oxide-graphene composite involves providing a composition comprising graphene oxide, at least one metal-containing substrate or at least one inert substrate, and a metal powder, the composition being dispersed in a liquid medium to form a mixture, where the mixture comprises a metal powder; forming the metal oxide-graphene composite; heating the composition; and/or cooling the composition. USE - The method is useful for making metal oxide-graphene composite used for article for devices, e.g. electrochemical sensors, chemical sensors, supercapacitors, lithium ion batteries, photocatalysts, or light emitting diodes (all claimed). ADVANTAGE - The metal oxide materials that include reduced graphene oxide have important applications in various fields, such as energy, electronics, information, and environment protection. The materials in thin film have increased response speed and sensitivity. Moreover, the formation of thin film can reduce cost by effectively reducing the amount of materials used. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a composition for making a metal oxide-graphene composite in situ, comprising at least one substrate; and graphene oxide; and (2) an article for devices comprising a metal oxide-graphene composite, where the devices comprise electrochemical sensors, chemical sensors, supercapacitors, lithium ion batteries, photocatalysts, or light emitting diodes.
