▎ 摘　　要

NOVELTY - A graphene composite material comprises a catalyst active center and two parts of graphene. The graphene is loaded on the graphene to form the composite material. USE - The method is useful for preparing graphene composite material, which is useful as cathode material for chemical power supply and battery, in energy storage and/or conversion, hydrogen storage in solid materials or hydrogen production or oxygen production, or preparing the cathode of a battery ( all claimed). ADVANTAGE - The graphene composite material converts the proton into hydrogen atom stored on the graphene by electrochemical method, which not only can realize the storage and release of hydrogen energy, hydrogen storage, hydrogen production and oxygen production, but also can be used as the cathode material of the chemical power supply, and constructing various types of battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing the grapheme composite material; (2) hydrogenated graphene composite material; and (3) use method of material for hydrogen storage in solid materials.
