| description | The invention discloses a preparation method of a foam metal/graphene/monatomic composite catalytic material. The preparation method comprises the following steps: (1) preparing a pure foam metal material from metal; (2) preparing graphene on the surface of the pure foam metal material through a chemical vapor deposition method; (3) on the basis of the foam transition metal/graphene composite material, depositing a transition metal layer on the surface of graphene by using a vacuum magnetron sputtering technology; and (4) eroding the foam transition metal/graphene/transition metal in dilute acid, cleaning, and drying to obtain the foam metal/graphene/monatomic composite catalytic material. According to the method disclosed by the invention, the flake defective graphene is prepared, the binding force of the graphene and a matrix is improved, the monatomic catalyst is captured through a large amount of flake defective graphene, the monatomic loading capacity is large, the structure is stable, the catalytic effe |
