▎ 摘　　要

NOVELTY - The method comprises (a) taking ruthenium chloride as active metal ruthenium source, chitosan as carbon and nitrogen source, zinc chloride as activating agent and pore-forming agent, respectively weighing ruthenium chloride, chitosan, and zinc chloride, dispersing in deionized water to obtain mixed solution, performing constant temperature stirring reaction, and drying to obtain solid, (b) grinding the solid into a tubular furnace, calcining under the protection of inert gas to obtain solid powder, and (c) adding the solid powder into hydrochloric acid, stirring at constant temperature for etching, filtering, washing, drying to obtain the ruthenium nanoparticles loaded on the composite material of nitrogen-containing porous layered carbon material. USE - The method is useful for preparing composite material for alkaline solution electrocatalytic hydrogen evolution (claimed). ADVANTAGE - The composite material: exhibits excellent catalytic performance in the hydrolysis hydrogen evolution under alkaline condition, and the performance is very stable; and utilizes the nitrogen-containing porous layered composite material with similar graphene structure with high graphitization degree, and is suitable for large-scale industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for composite material for electrocatalytic hydrogen evolution of alkaline solution prepared by the above method.
