Abstract

Due to the formation of abundant hydroxyl groups on the TiO2 support, water in the ball-milling process promoted the dispersion of vanadia species on V2O5/TiO2 catalysts. Therefore, a high ratio of polymeric vanadyl species and strong redox capability were obtained for the vanadia-based catalyst, which led to good NH3-SCR activity.
