▎ 摘　　要

NOVELTY - Preparation of tungsten oxide-graphene composite material involves adding water to graphene oxide to make graphene oxide aqueous solution, adding tungsten solution dissolved in ethanol into the graphene oxide aqueous solution for mixing to obtain a mixed solution, adding acetone while stirring the mixture and generating mixture under microblogging conditions, washing and drying the mixture, heating the mixture, and grinding after cooling. USE - Preparation of tungsten oxide-graphene composite material used in gas detection (claimed). ADVANTAGE - The method improves the efficiency of the tungsten oxide-graphene composite materialcomposite material of tungsten oxide preparation graphene.
