▎ 摘  要

NOVELTY - A graphene-coated alloy nanocatalyst comprises metal alloy nanoparticles (I), and graphene or non-metallic element-doped with graphene coated on the surface of compound (I). USE - The graphene-coated alloy nanocatalyst is useful for the conversion of carbon dioxide to carbon monoxide (claimed). ADVANTAGE - The graphene-coated alloy nanocatalyst has excellent surface electron density, and can enhance the adsorption and activation of carbon dioxide reactant molecule. DETAILED DESCRIPTION - A graphene-coated alloy nanocatalyst comprises metal alloy nanoparticles of formula: AxB1y (I), and graphene or non-metallic element-doped graphene coated on the surface of compound (I). A, B1=metal elements, preferably Fe, Co, Ni or Cu, where the mass ratio of x and y is (1-9):(9-1). INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene-coated alloy nanocatalyst, which involves uniformly mixing metal powder (A) and metal powder (B), filling mixed mixture in an inside of metal pipe to form anode, using graphite rod as cathode, which is opposite to the anode, and subjecting the reaction chamber containing methane or mixed gas of methane and dopant gas to arc discharge reaction at 20-60 Angstrom for 1-6 hours; and (2) use of graphene-coated alloy nanocatalyst for the conversion of carbon dioxide to carbon monoxide.
