NOVELTY - Method for growing metal phosphide on surface of graphene by microwave method, involves (a) preparing a graphene oxide aqueous solution at a concentration of 0.1-0.5 g/l, (b) dissolving metal nickel salt solution in the graphene oxide aqueous solution, mixing, uniformly stirring, transferring the obtained mixed solution to a microwave reactor, heat-preserving at 20-30 degrees C for 5-20 minutes, heating at 40-50 degrees C for 5-20 minutes, heating at 60-70 degrees C for 5-20 minutes, heating at 75-85 degrees C for 5-20 minutes, heating at 90-100 degrees C for 5-20 minutes, cooling to room temperature, centrifuging, washing, and freeze-drying to obtain a product (A), and (c) placing the product (A) and phosphorus source in a tube furnace, heating at 300-600 degrees C for 1-4 hours under the protection of an inert gas atmosphere, and naturally cooling to room temperature to obtain the material. USE - The method is useful for growing metal phosphide on surface of graphene to prepare the metal phosphide-graphene composite material used as bifunctional catalyst for catalytic hydrogen electrolysis to produce hydrogen and/or oxygen (all claimed), and as supercapacitor material, battery material and catalytic material. ADVANTAGE - The method uniformly disperse the active material in the product on the surface of the graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for use of the metal phosphide-graphene composite material prepared by the above-mentioned method as a bifunctional catalyst for catalytic hydrogen electrolysis to produce hydrogen and/or oxygen.
