Pr-TiO2 nanoparticles were prepared by using a sol-gel method. As-prepared samples were characterized by BET measurements, X-ray powder diffraction analysis (XRD) and UV-Vis spectra. Visible and ultraviolet light photocatalytic activity of the sample was studied by photodegradation of phenol, while considering the influence of the dopant concentration. TiO2 doped with 0.25 mol% of praseodymium showed the highest photocatalytic activity under visible light irradiation. Pr-TiO2 had anatase structure. The surface area was higher for powders with higher content of rare earth metal ion, and ranged from 121 to 150 m2/g. Red shifts of absorption edge toward the visible region were observed for the doped samples compared to pure TiO2.
