NOVELTY - In-situ preparation and application of two-dimensional graphene-type nickel-molybdenum nitride composite material comprises mixing sodium molybdate, nickel(II) nitrate hexahydrate, ammonium fluoride urea and ultrapure water evenly, adding the treated foamed nickel, and obtaining a two-dimensional graphene-type nickel-molybdenum nitride composite material, two-dimensional graphene-type nickel-molybdenum nitride composite material is prepared by (a) dissolving sodium molybdate, and nickel(II) nitrate hexahydrate in ultrapure water, adding the treated Nickel foam, and transferring to a hydrothermal reaction vessel (transferring to a polyvinyl fluoride-lined stainless steel hydrothermal reaction kettle), heating solution for 6 hours and drying under vacuum to obtain the precursor; and (ii) adding precursor in a tube furnace under the protection of gas atmosphere, baking and cool ingto room temperature. USE - The material is useful for electrocatalytic hydrogen production at room temperature (claimed). ADVANTAGE - The two-dimensional graphene nickel-molybdenum nitride composite material exhibits a high electrocatalysis hydrogen evolution reaction characteristics the alkaline electrolyte. The preparation method is simple, environment-friendly, low in characteristics, and can be prepared in large scale characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing electrocatalytic hydrogen at room temperature.
