▎ 摘　　要

NOVELTY - Preparing graphene stabilized ultra-small size copper-nickel nanocomposite comprises taking graphene oxide, nickel salt and copper salt, adding solvent, mixing uniformly, adding alkali liquid, heating and reacting in an oil bath pot, where the reaction temperature is 180 degrees C and the reaction time is 15 minutes, centrifuging after completion of the reaction, washing, and collecting the product, where the total mass ratio of graphene oxide, copper salt and nickel salt is 1:0.001-1:0.004. USE - The method is useful for preparing graphene stabilized ultra-small size copper-nickel nanocomposite (claimed). ADVANTAGE - The method is simple (claimed), produces reaction intermediate without toxic and explosive hydrazine hydrate as a reducing agent, produces product with small particle size, morphology, stability and high purity, and is suitable for medium-scale industrial production.
