▎ 摘　　要

NOVELTY - The method comprises using a high-temperature substrate, quenching the metal salt solution with a liquid carbon source solution under the protection of an inert atmosphere, cooling the high temperature substrate on the surface of the base substrate to obtain a quenched liquid, heating and decomposed the metal salts in the quench solution to form a metal nano particles, and heating and decomposing the solution of the liquid carbon to form graphene on the substrate surface to grow graphene, so as to quickly prepare the graphene material. USE - One-step ultra-fast preparation method of graphene material loaded by metal nano-particle including industrial catalysis, Raman enhancement, high-entropy alloy, gas sensing and electromagnetic shielding. ADVANTAGE - The method has simple preparation technique, high efficiency, low cost, good controllability, quickly prepares multiple metal nano-particle loaded graphene material, the material in the photoelectric catalysis, industrial catalysts, Raman enhancement, high-entropy alloy, gas sensing, electromagnetic shielding and other fields of application. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the one-step ultra-fast preparation method of graphene material loaded by metal nano-particle.
