Abstract

Tungsten and tungsten-carbon doped titania particles were successfully synthesised by a simple solvothermal method using WCl6 as W source and titanium tetra-n-butoxide/ethanol as C source. With the incorporation of W in TiO2 lattice, the near infrared absorption property of W-TiO 2 samples was strongly promoted. Furthermore, the visible light absorption capability of TiO2 based samples was also greatly affected by codoping C in W-TiO2. More importantly, the C-W codoped TiO 2 samples presented excellent continuous toxic NO gas destruction ability much superior to those of undoped TiO2, solely C and W doped TiO2 as well as commercial P25 titania under the irradiation of UV and visible lights. The near infrared absorption performance and photocatalytic activity of TiO2 based products could be effectively controlled by W doping and C-W codoping, which probably have a promising application in the field of environmental protection and near infrared light shielding.
