▎ 摘  要

NOVELTY - Preparing ruthenium element-modified sulfur-doped graphene two-dimensional material, comprises (i) adding ruthenium chloride hexahydrate and graphene oxide into deionized water, and adjusting the pH to 0-6 with sulfuric acid, and uniformly dispersing by ultrasonic vibration, then freeze-drying to remove the solvent to obtain a solid, and (ii) calcining the solid in an inert atmosphere at high temperature, cooling to room temperature, pickling, washing with water, and drying. USE - The graphene two-dimensional material is useful as electrocatalyst for hydrogen production from water electrolysis (claimed). ADVANTAGE - The graphene two-dimensional material: has excellent conductivity; can be uniformly distributed; and has low overpotential, high catalytic activity and long catalytic life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for ruthenium element-modified sulfur-doped graphene two-dimensional material prepared by the above method.
