▎ 摘　　要

NOVELTY - The porous metal/three-dimensional graphene composite has a porous metal substrate, three-dimensional graphene on the porous metal, multiple nanoparticles/nanowires and/or nanofilm attached to the three-dimensional graphene. USE - Porous metal/three-dimensional graphene composite. ADVANTAGE - The realization of nano-material composite from zero-dimensional to three-dimensional fully combines the advantages of the above-mentioned various sizes of nano-materials and avoids the disadvantages of each material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for manufacturing porous metal/three-dimensional graphene composite material; and (2) an electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the three-dimensional graphene on the porous metal in the porous metal/three-dimensional graphene composite.
