Study on Preparation of ZnO-TiO2 Composite Photocatalyst and its Properties

Abstract:

Using titanyl sulfate and zinc sulfate and others as the main resources, we adopted separately sluggish precipitation method and co-precipitation method to prepare pure TiO2 nano-powder and ZnO-TiO2 nano-composite photo-catalytic materials. The authors used X-Ray Diffraction (XRD) to research crystal types of the TiO2 nano-powder and ZnO-TiO2 nano-composite photo-catalytic materials, and conducted experiments of photo-catalytic performance and light absorption performance of the samples that were made. The experiment results showed that the prepared TiO2-ZnO nano-composite photo-catalytic materials are relatively ideal. The paper used visible light as the light source to realize the effective degradation of the organic matters.
