Abstract:

ZnO-graphene nanocomposite materials can effectively promote the separation of electrons and holes,and possesses large specific surface area. It is beneficial to the diffusion and mass transfer of pollutants and free radicals. Electrons can directly be transferred from the ZnO high-energy conduction band of holes to grapheme,and can also improve the photo-catalytic capacity of composite materials under UV or visible light. Therefore,ZnO-graphene nano-composite materials have widely been researched in photo-catalysis field. The preparation of ZnO-graphene nano-composite materials and the latest research progress in its application to the photo-catalytic degradation of pollutants are summarized.

Key words: graphene, ZnO, nano-composites, photocatalysis
