▎ 摘　　要

NOVELTY - Preparing porous metal/graphene composite material comprises (i) using chemical method to prepare the graphene oxide sol, (ii) taking graphene oxide sol mixed metal salt aqueous solution, drying self-assembling into metal salt/oxidation graphene film, (iii) metal salt/oxidation graphene film by means of mechanical shearing crushing into small pieces, and (iv) under the reducing atmosphere, taking small fragment, raising the temperature to 300-600 degrees C, thermal insulating for 5-240 minutes to obtain porous metal/graphene composite. USE - The method is useful for preparing porous metal/graphene composite material (claimed). The composite material is used in electric, light catalytic hydrogen storage material, hydrogen storage material, and dye-sensitized solar cell. ADVANTAGE - The method is safe, has simple operation, obtains porous metal/RGO complex directly through the hydrogen reduction and peeling action of the generated gas.
