Abstract
In this research, silver was loaded onto ZnO using the photoreduction method to enhance the photocatalytic activity of ZnO in the visible region. The photocatalytic activity of ZnO and Ag/ZnO was investigated for the gas-phase degradation of volatile organic compounds such as ethyl acetate, ethanol, and toluene under visible light irradiation. The Ag/ZnO effectively decomposed ethyl acetate, toluene, and ethanol separately and in a mixed state. The characteristics of Ag/ZnO and ZnO were studied using XRD, SEM, EDAX, XPS, BET, UV–vis DRS, and PL analyses. The XRD pattern confirmed the formation of metallic silver in the Ag/ZnO photocatalyst. The PL results showed that the loading of Ag on the ZnO significantly reduces the photoelectron-hole pairs recombination in Ag/ZnO.
