NOVELTY - The preparation of tungsten trioxide/nitrogen-doped graphene composite involves adding corresponding amount of ammonium tungstate with appropriate amount of ammonium nitrate and organic fuel, dissolving in a small amount of water, adding corresponding volume of 0.5-5 g/l graphene oxide hydrosol, ultrasonically stirring to obtain uniform mixed dispersion, heating dispersion and concentrating to a viscous state, placing in a furnace, heating at 300-900 degrees C, and carrying out combustion. USE - Preparation of tungsten trioxide/nitrogen-doped graphene composite. ADVANTAGE - The method enables preparation of tungsten trioxide/nitrogen-doped graphene composite with high efficiency, simple equipment and high yield under low synthesis temperature by simple and economical process.
