▎ 摘 要
NOVELTY - Graphene oxide-based nitrogen-doped porous carbon-coated ruthenium-cobalt phosphide composite material comprises using graphene oxide, cobalt salts, ruthenium salts, organic ligands and nitrogen sources as raw materials, and obtaining ruthenium through a hydrothermal method cobalt bimetallic organic framework/graphene oxide composite RuCo-MOF/GO, and calcining with phosphorus source to achieve phosphating and carbonization, and graphene oxide-based nitrogen-doped porous carbon-encapsulated ruthenium phosphating can be prepared Cobalt composite Ru-Co-P doped NC/GO. USE - Used as graphene oxide-based nitrogen-doped porous carbon-coated ruthenium-cobalt phosphide composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing graphene oxide-based nitrogen-doped porous carbon-coated ruthenium-cobalt phosphide composite material comprises (1) preparing RuCo-MOF/GO, with graphene oxide, cobalt nitrate hexahydrate, 1,4-phthalic acid, dicyandiamine and ruthenium trichloride hydrate meeting a certain mass ratio, first Alene, cobalt nitrate hexahydrate, 1,4-phthalic acid and dicyandiamine were dissolved in N,N-dimethylformamide and stirred to form solution A, ruthenium trichloride hydrate was dissolved in water and stirred to form a solution A into solution B, mixing solution A and the solution B mixed to obtain a reaction solution, and finally, a hydrothermal reaction is carried out under certain conditions, and the obtained product is cooled to room temperature, washing with absolute ethanol/water, centrifuging, and drying in vacuum to obtain ruthenium cobalt bimetal organic framework/graphene oxide composite, named RuCo-MOF/GO, (2) the preparation of Ru-Co-P doped NC/GO, using the RuCo-MOF/GO obtained in step (1) and hypophosphite, mixing sodium and RuCo-MOF/GO and sodium hypophosphite, placing under certain conditions, and calcining under certain conditions to achieve phosphorus, cooling obtained product to room temperature, can be obtained by grinding to graphene oxide-based nitrogen-doped porous carbon-encapsulated ruthenium-cobalt phosphide composites material, named Ru-Co-P doped N-C/GO.
