description The invention relates to a graphene supported nickel nano particle composite material and a preparation method thereof, and mainly relates to the field of graphene. According to the method, functional groups on graphene oxide surface are increased by surface treatment of graphene oxide, and combination points of metal ions and the graphene oxide can be enlarged; by adding of D-L malic acid, a metal nickel salt and other surfactants, attaching of the metal ions on the graphene oxide surface can be promoted; by using of sodium borohydride as a reducing agent, use of hydrazine, hydrazine derivatives and other strong toxicity reducing agents can be avoided, and the environmental friendliness of the composite material is improved; in addition, the preparation method can be carried out at room temperature, and energy consumption is reduced. By nickel nanoparticles in the graphene supported nickel nano particle composite material prepared by the preparation method are dispersed uniformly, and the load amount is cont
