Abstract:

Yellow colored anatase Fe/N co-doped TiO₂ powders have been successfully synthesized by one step hydrothermal method at a lower temperature. The grain size was about 10 nm and the specific surface area of the powders ranged from 160 to 166 m²/g. The light absorption of Fe/N co-doped TiO₂ powders was enhanced in the visible light region of 400~500 nm and a new absorption peak at about 470 nm appeared when the Fe/Ti ratio exceeded 0.5%. The visible light photoactivity of Fe/N co-doped TiO₂ powders has been greatly improved than that of un-doped TiO₂ powders under visible light irradiation.
