Nanostructured Fe-Ti02 and Ti02 with anatase structure were synthesized via combination method of sol- gel and peptization process. The samples were characterized by X-ray diffraction (XRD), Transmission emission microscopy (TEM) and UV-Vis spectroscopy (UV-Vis). The presence of Fe3+ ion shifted the absorption profile of Ti02 to the longer wavelength side of the spectrum, indicating an obvious photocatalytic activity under visible irradiation. Photocatalytic activity of the samples were evaluated by methyl orange (MO) discolouration under UV-light irradiation. Compared with the pure Ti02 nanoparticles, the Fe-Ti02 nanoparticles exhibited higher photocatalytic activity with 95% discoloration within 2 h.
