| Abstract: | The iron\|doped titania catalysts were prepared by sol\|gel method, and characterized by XRD, UV\|Vis diffuse reflection spectra. Their photocatalytic activities were tested by degradation of nitrite.The results indicated that the iron\|doped samples cause changes in crystalline phase and particle sizes of the titania. Samples containing low amount of iron (3 0%) were more effective for nitrite oxidation than pure TiO\-2. |
