摘要：
The V-doped TiO2 nanoparticles were successfully prepared by sol-gel method and characterized by X-ray diffraction (XRD), UV-vis spectroscopy and photoluminescence (PL) spectroscopy respectively. It is found that doping V can shift the absorption edge to the visible light region and decrease the recombination of photo-induced electron-hole pairs. Then the photo-absorption and photocatalytic activity were greatly improved. The optimal doping concentration is 0.5% due to synergetic effect of the recombination of electron-hole pairs and adsorption of dyes molecules at the surface of samples.
