NOVELTY - Preparing graphene supported nitrogen and boron doped nickel phosphide electrolysis water catalyst involves forming boron-nickel oxide/graphene as precursor by using gas-phase synthesis method, using nickel nitrate, graphene oxide and sodium borohydride as reactants. The boron-nickel oxide/ graphene obtained are dried and weighed certain amount of NaH2PO2. The boron-nickel oxide/graphene and weighed NaH2PO2 together are added in quartz boat, and protects them with ammonia/argon mixed gas under heating to obtain final product. USE - Method for preparing graphene supported nitrogen and boron doped nickel phosphide electrolysis water catalyst. ADVANTAGE - The method enables to prepare graphene supported nitrogen and boron doped nickel phosphide electrolysis water catalyst that solves technical problem of preparation of novel inorganic nano-functional materials.
