NOVELTY - Preparation of graphene oxide-supported ruthenium(IV) oxide-cobalt phosphide involves reacting graphene oxide-loaded zeolitic imidazolate framework-67 (ZIF-67) and ruthenium trichloride hydrate in water, collecting precipitate in the reaction solution, and placing the precipitate in an inert atmosphere for high-temperature phosphating. USE - Preparation of graphene oxide-supported ruthenium(IV) oxide-cobalt phosphide used for preparing hydrogen evolution catalyst e.g. metal hydride hydrolysis hydrogen evolution catalyst (all claimed). ADVANTAGE - The method enables preparation of graphene oxide-supported ruthenium(IV) oxide-cobalt phosphide with high hydrogen evolution rate and stability for catalytic hydrolysis of sodium borohydride.
