Study on a thorough treatment of organic compounds in the polluted environment is always a prime concern of each country. In this study, silver nano doped on TiO2 (Ag nano/TiO2) samples with different initial Ag concentrations in the range of 0.5‐3 % were synthesized by electron beam irradiation method. The synthesized Ag nano/TiO2 material was characterized by transmission electron microscopy (TEM), X‐ray diffraction (XRD) and Brunauer‐Emmett‐Teller measurement (BET). The size of Ag nanoparticles was in the range of 2 ‐ 30 nm. The photocatalytic activity of Ag nano/TiO2 materials with different initial Ag contents for Rhodamine B (RhB) decomposition was also investigated. The photocatalytic efficiency of RhB degradation by Ag nano/TiO2 material was higher than that of TiO2 about 33% after 2.5 hours under visible light irradiation.
