▎ 摘　　要

NOVELTY - Growing copper-based multilayer graphene comprises (i) pre-treating copper foil substrate and placing into the support, (ii) coating with metal foil on the outside of the support, (iii) placing the above-mentioned metal foil-clad stent into a vacuum system and annealing, and (iv) reacting with carbon-containing gas for 30-60 minutes, cooling and forming multilayer on the surface of the copper foil. USE - The method is useful for growing copper-based multilayer graphene. ADVANTAGE - The method: is simple and safe; has fast growth rate; improves the catalytic decomposition efficiency; increases the concentration of carbon atoms; has no additional energy consumption; can form high quality; and has high multi-layer graphene.
