NOVELTY - Preparation of nickel-ruthenium/graphene oxide double-metal catalyst comprises dissolving nickel nitrate hexahydrate in deionized water, ultrasonically stirring and dissolving, adding graphene oxide, stirring into paste, dipping and stirring for preset time, drying to obtain first catalyst, putting first catalyst into tubular furnace and roasting for preset time by nitrogen, introducing hydrogen for metal reduction, and preparing nickel (Ni)/graphene oxide (GO) metal catalyst; and dissolving ruthenium chloride trihydrate in deionized water, stirring, pouring Ni/GO metal catalyst, stirring into paste, dipping and stirring, drying to obtain second catalyst, putting second catalyst into tubular furnace for roasting through nitrogen, and introducing hydrogen for metal reduction. USE - The method is used for preparing nickel-ruthenium/graphene oxide double-metal catalyst (claimed).
