▎ 摘  要

NOVELTY - The preparation of reduced tungsten oxide/nitrogen-doped graphene composite which involves weighing the corresponding amount of ammonium tungstate with appropriate amount of ammonium nitrate and organic fuel, dissolving in small amount of water, adding corresponding volume of 0.5-5 g/l graphene oxide hydrosol, stirring, ultrasonically treating to obtain uniform mixed dispersion according to the preparation amount of the reduced tungsten oxide/nitrogen-doped graphene composite and the content of the reduced tungsten oxide, heating the dispersion and concentrating to a viscous state, placing in heating furnace at temperature of 300-900 degrees C for combustion, collecting the combustion products, placing the combustion product in 5% nitrogen-hydrogen mixed gas atmosphere furnace at 500-800 degrees C for 60-240 minutes, and cooling to room temperature. USE - Preparation of reduced tungsten oxide/nitrogen-doped graphene composite. ADVANTAGE - The method enables industrially production of reduced tungsten oxide/nitrogen-doped graphene composite with high efficiency, uniform morphology and high yield by simple and economical process.
