In recent years many efforts have been made to use sunlight for energy production, water purification and environmental protection, in which photocatalysis plays a crucial role. Photocatalysis is a potential new method capable of eliminating relatively stable organic compounds. This method is based on the production of electron hole pairs by irradiation with light sources, of a semiconductor material such as transitional metal structures dispersed in an aqueous solution. In the last century, many scientists felt that irradiation was a faster way for catalyzing a reaction, compared to a chemical reaction. Nowadays, the increased pollution of water bodies by chemicals and wastewater treatment has become the most important crisis, because large quantities of synthetic pollutants are continually discharged into our environment [1–3]. For this reason, it is necessary to remove these chemicals from wastewaters before their discharges to water sources. Among different strategies applied photocatalysis is an efficient route for the reduction of these organic pollutants [4,5]. Among various semiconductors, ZnO is the second most popular photocatalyst with cheap price, high stability, and also nontoxic. However, this type of semiconductor suffers some limitations such as poor visible-light response and fast recombination rate of the produced electron hole pairs [6]. To overcome these issues, the fabrication of heterojunction between this semiconductor and other semiconductors possessing high photosensitivity to visible light has been proposed to improve the photocatalytic performance of ZnO [7]. In this study, ZnO doped Ag has been successfully synthesized and characterized (SEM, TEM, XRD) then incorporated in a photopolymerized matrix to be tested by the determination of photocatalytic degradation of an organic dye solution.
