In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and germs. Nowadays, nano structures used for detection and removal of chemical and biological substances include metals, azo dyes, nutrients, cyanide, organics, algae, bacteria, parasites, and etc. In the current study, an attempt is made to synthesize and characterization of Ag dope PbTiO3 nano particles in an aqueous environment through the two-step sol-gel method. Besides, glucose, lactose, and starch were applied as the natural capping agents and their effect on the morphology and particle size of final products were investigated by SEM analysis. The structural, morphological, and optical properties of as-obtained products were characterized by techniques such as XRD, SEM, EDX, and UV-vis spectroscopy. In addition, in order to evaluate the photo catalytic properties of nano crystalline Ag dope PbTiO3, the photo catalytic degradation of simulated methyl orange dye wastewater under ultraviolet light irradiation were carried out. Furthermore, the photo catalysis results reveal that the maximum decolonization of 74 and 66 % for methyl orange occurred with Ag dope PbTiO3 and PbTiO3 samples in 90 min under ultraviolet (UV) light irradiation, respectively.
