Recently, TiO2 is one of the most important materials in the field of photocatalytic activity. In the present study, Co-TiO2, Nd-TiO2, and Co,Nd-TiO2nanocomposites powders were prepared via sol-gel method. Moreover, the advantage of metal doping and co-doped effects on photocatalytic activity were investigated. Structure and photocatalytic activity were studied by several methods such as: FT-IR spectra, Scanning Electron Microscopy (SEM), and X-Ray Diffraction (XRD). The results have revealed that Co,Nd-codoped TiO2 nanocomposite has better photocatalytic activity in comparison with Co-doped TiO2 and Nd-doped TiO2nanocopmosites.
