▎ 摘 要
NOVELTY - A cubic phase cobalt/graphene composite material has monocrystalline structure, and comprises metal cobalt as face-centered cubic structure, and graphene as sheet-shaped structure. The molar ratio of carbon and cobalt in cubic phase cobalt/graphene composite material is 3:2. USE - Cubic phase cobalt/graphene composite material is used as absorbing material (claimed). ADVANTAGE - The cubic phase cobalt/graphene composite material has excellent absorbing property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of cubic phase cobalt/graphene composite material.
