Abstract: Photocatalysis defined as is one of the different types of AOPs, ecologically friendly processes have a major advantage over certain current techniques; it terminates contaminations instead of exchanging them to another phase without the utilization of potentially harmful oxidants. So as to increase their activity, photocatalysts have been doped with many metals, non-metals, and noble metals. Through a different metal was used for this aim, silver (Ag) suggested to be the most attractive in relations of photocatalytic production. Textile wastewater is classified as a complex treatment waste due to high organic pollution and metals, high toxicity and low biodegradation. In addition, dyes are discussed in the literature because of the large quantities of dyes and water used in the dying stages during the textile sector. In this study, we used the photochemical deposition method to synthesize Ag/TiO2 catalyst. The physical and chemical properties of the Ag/TiO2 catalyst characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and EDX. The Ag/TiO2 catalyst was used to remove the most commonly used reactive red 195 dye in the textile industry. The removal was investigated using photocatalytic oxidation method with different light types such as UV-A and visible light.
