Preparation of Graphene/WO3 Nanocomposite and Its Application in Photocatalytic Degradation

Graphene/semiconductor nanocomposites were prepared by hydrothermal method, and the photocatalytic degradation performance of the composite was investigated. The mechanism of photocatalysis is proposed and analysed. It is believed that graphene can effectively improve the separation efficiency of photogenerated electron-hole pairs, improve the physical structure and light absorption performance of the catalyst, thereby improving the photocatalytic activity and degradation efficiency. Finally, the possible development trend of this kind of materials in the future was proposed.
