Study on Photocatalytic Degradation of Pollutants by Zinc Oxide Nanocomposites

Abstract

In recent years, the research of zinc oxide nanocomposites has attracted much attention. Due to the high probability of photonized carrier recombination of a single nanometer zinc oxide material, and the low utilization of sunlight, its application in the degradation of pollutants is limited. Compounding zinc oxide with other materials can solve this problem. In this paper, through the study of the photocatalytic properties of zinc oxide nanocomposites, the synthesis methods and photocatalytic properties of TiO2/ZnO and ZnO/graphene nanocomposites are reviewed. Nanocomposite photocatalytic degradation mechanism of pollutants and its application in the degradation of pollutants.
