▎ 摘  要

NOVELTY - Reduced graphene oxide supported bimetallic nanocluster catalytic material includes reduced graphene oxide as a carrier. The ruthenium (III) and nickel (II) are reduced to ruthenium-nickel bimetallic nanoclusters under the action of polyvinylpyrrolidone to obtain ruthenium-nickel bimetallic nanoclusters supported reduced graphene oxide composites. USE - Reduced graphene oxide supported bimetallic nanocluster catalytic material. Adv: --- ADVANTAGE - The reduced graphene oxide supported bimetallic nanocluster catalytic material has a conversion rate of complete hydrogen evolution of 400-600 molH2.molRu-1.min-1, the hydrogen production rate is 10300-20000 mL.min-1.mmol-1, and the amount of hydrogen released is 80-90% of the theoretical value, activation energy of catalytic hydrogen desorption of 21-26 kJ.mol-1, and 82-83% maintained initial catalytic activity, and improved cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing reduced graphene oxide supported bimetallic nanocluster catalytic material, which involves placing reduced graphene oxide powder in water under stirring ultrasonically to obtain a reduced graphene oxide dispersion liquid with a certain solute mass fraction recorded as solution A, dissolving ruthenium trichloride hydrate and nickel chloride hexahydrate in water with polyvinylpyrrolidone under stirring to obtain Ru-Ni dipping solution as solution B, mixing solution A and solution B to form solution C, dissolving ammonia borane in water to obtain a certain concentration of ammonia borane aqueous solution under certain conditions, fully mixing the ammonia borane aqueous solution and the obtained solution C to obtain catalytic material for reducing graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope graph of the Reduced graphene oxide supported bimetallic nanocluster catalytic material.
