This work reports sol-gel synthesis of ternary mixed metal oxide nanoparticles comprising TiO2, ZnO, and Bi2O3. The structure and morphology of the nanoparticles were studied using XRD and FESEM. The Studying of optical properties of the nanoparticles showed the potential of the synthesized nanoparticles serving as an efficient photocatalyst for degradation of pollutant. It was found that the incorporation of Bi2O3 and ZnO has considerable impact on reducing of the TiO2 band gap to 2.64 eV. The photocatalytic activity of the nanoparticles was investigated by visible light degradation of aqueous solution of methylene blue (MB). After 180 min illumination under visible light, the synthesized mixed metal oxide nanoparticles degraded the MB solution by 87%. Effect of different determinants, such as amount of photocatalyst, concentration of H2O2, and pH of MB solution, on the photocatalytic degradation of MB was studied.
