NOVELTY - Synthesis of three-dimensional graphene-reinforced nickel based composite material involves taking glucose or citric acid, nickel nitrate hexahydrate and soluble salt template sodium chloride, mixing, dissolving in deionized water, freeze-drying, grinding, synthesizing at 600-800 degrees C under argon and hydrogen mixed gas, cooling to room temperature, mixing, washing, removing sodium chloride, drying, dissolving nickel nitrate hexahydrate in anhydrous ethanol, dissolving prepared mixture, drying at 75 degrees C, vacuum drying at 55 degrees C, coating on three-dimensional graphene, and heating at 400-500 degrees C. USE - Method for synthesizing three-dimensional graphene-reinforced nickel based composite material. DETAILED DESCRIPTION - Synthesis of three-dimensional graphene-reinforced nickel based composite material comprises taking glucose or citric acid, nickel nitrate hexahydrate and soluble salt template sodium chloride, mixing, dissolving in deionized water, freeze-drying, grinding, synthesizing at 600-800 degrees C under argon and hydrogen mixed gas, cooling to room temperature, mixing, washing, removing sodium chloride, drying, dissolving nickel nitrate hexahydrate in anhydrous ethanol, dissolving prepared mixture, drying at 75 degrees C, vacuum drying at 55 degrees C, coating on three-dimensional graphene, heating at 400-500 degrees C, cooling, molding, and sintering at 700-800 degrees C. Mole ratio of nickel and carbon is 1:5-50.
