Effective photocatalytic decomposition of VOC under visible-light irradiation on N-doped TiO2 modified by vanadium species

Photocatalytic activity of nitrogen-doped TiO2 (N-TiO2) will greatly increase by adding vanadium species for the decomposition of various volatile organic compounds (VOC) under both visible light and UV-light irradiation. The added vanadium species having oxidation states between +IV and +V that interact with surface N-TiO2 play significant roles as redox mediators in the enhancement of photocatalytic activity.
