Synthesis, Characterization and Photocatalytic Performance of ZnO/TiO₂ and ZnO/TiO₂/CuO Nanocomposite

Abstract:

In the present study, an attempt was made to synthesize ZnO/TiO₂ and ZnO/TiO₂/CuO nanocomposites as photocatalyst for degradation of organic pollutant (methylene blue) in aqueous solution under UV and visible light irradiation. Characterization using X-ray diffraction, energy dispersive X-ray spectroscopy, field emission scanning microscope electron, diffuse reflectance spectroscopy analysis confirmed that all three components phase are present in the photocatalyst. The photodegradation of organic pollutant showed that with the incorporation of CuO content in ZnO/TiO₂ nanocomposites increasing the photocatalytic performance in ultraviolet as well as visible region.
