In this work firstly ZnO nanoparticles were synthesized via a simple precipitation method. At the second step titanium dioxide and silicon dioxide shell were synthesized on the core. For preparation ZnO–TiO2–SiO2 the sol product was calcinated at 500 ºC for 2h. Properties of the product were examined by X–ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform infrared (FT–IR) spectroscopy. The photo– catalytic behavior of ZnO–SiO2–TiO2 nanocomposite was evaluated using the degradation of a methylene blue aqueous solution under visible light irradiation. The results show that ZnO–SiO2–TiO2 nanocomposites have applicable photo–catalytic performance.
