| Abstract | TiO2/SiO2 and TiO2/SiO2/Ni nanocomposite powders were prepared by a sol-gel technique. Moreover, different concentrations of dopant were added to investigate the effect of the metal doping effect. Structures were characterized by IR spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX) and X-Ray Diffraction (XRD) methods. Moreover, the absorption coefficients of the samples were analyzed by Tauc's approach and the direct band gaps also were calculated. The photocatalytic activity of all the samples was investigated under UV irradiation in an aqueous medium. The results revealed that metal doping plays an important role in decreasing the particle size. Furthermore, photocatalytic activity improves in the presence of a dopant. |
