▎ 摘　　要

NOVELTY - The method comprises adding the ethanol into the oxidized graphene solution, stirring, ultrasonic to obtain the oxidized and o graphene mixed solution, dissolving the copper salt and molybdate in the deionized water, stirring to form uniform dark green solution, slowly dropping the mixed solution A to obtain the mixed graphene A, dissolving the sulfur source, nitrogen source and polyvinylpyrrolidone in the mixed solution A, vigorously stirring to obtain the precursor mixed solution B, transferring the precursor mixed solution B to the reaction vessel, carrying out hydrothermal reaction in the oven, washing the obtained hydrothermal reaction sample, freezing and drying and collecting to obtain the final product Cu-MoSx/N, S-rGO. USE - Method for preparing nitrogen and sulfur co-doped graphene copper-molybdenum sulfide catalyst useful in the field of material and energy chemical industry. ADVANTAGE - The nitrogen-sulfur co-doped graphene copper-molybdenum sulfide catalyst has high catalytic activity and stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: A nitrogen-sulfur co-doped graphene copper molybdenum sulfide catalyst; and An application of the nitrogen-sulfur co-doped graphene copper-molybdenum sulfide catalyst.
