Abstract

Nitrogen-doped titania (TiO2) photocatalyst were prepared by a simple sol-gel method using tetrabutyl titanate and triethylamine as precursors. The photocatalytic decomposition of methyl orange (MO) solution was used as a probe reaction to estimate the photocatalytic activity under ultraviolet and simulated visible light irradiation. The physical and photophysical properties of the photocatalyst were characterized by XRD, UV-Vis DRS and XPS. The results indicate that the simulated visible light photocatalytic ability of catalysts is improved, especially the nitrogen-doped sample calcined at 500 (N500) showed excellent photocatalytic activity for methyl orange (MO) degradation under simulated visible light irradiation ,which could be attributed to the nitrogen doping.
