The V2O5/TNT (VTNT) catalysts were obtained by impregnation in NH4VO3 solution. The VTNTs exhibited much higher denitration efficiency than those supported on the raw TiO2, and satisfactory resistance to water and sulfur. Results from BET, TEM, XRD, NH3-TPD and EPR verified that V2O5 was dispersed well on TNT, thus favoring NH3 adsorption, promoting the transformation from V5+ to V4+, conducing to the formation of oxygen vacancies and superoxide radicals in the presence of NH3 and O2, and then resulting in the high catalytic activity of VTNTs.
