▎ 摘  要

NOVELTY - The method for preparing tungsten disulfide/nitrogen-sulfur co-doped graphene composite, involves (1) weighing the corresponding amount of ammonium tungstate with appropriate amount of ammonium nitrate and organic fuel, dissolving in small amount of water, adding 0.5-5 g/L graphene oxide hydrosol and ultrasonically stirring to obtain uniform mixed dispersion, (2) heating the dispersion and concentrating to be viscous, placing in heating furnace at temperature of 300-900 degrees C, obtaining solid product, (3) adding solid product and sulfur source compound and mixing to obtain mixture, (4) placing the mixture in an atmosphere furnace with nitrogen or argon gas at 500-1100 degrees C, vulcanizing for 30-180 minutes, cooling to room temperature and collecting solid product. USE - Method for preparing tungsten disulfide/nitrogen-sulfur co-doped graphene composite. ADVANTAGE - The method enables simple and economical preparation of tungsten disulfide/nitrogen-sulfur co-doped graphene composite with high efficiency and high yield.
