  • A series of V2O5-MoO3/TiO2 and V2O5-MoO3/TiO2-ZrO2 catalysts were prepared by impregnation method. The effects of V2O5/TiO2, MoO3/TiO2 and ZrO2/TiO2 mass ratio on the selective catalytic reduction of NO were investigated. The results showed that the V3M6TZ-30% catalyst had the best denitration activity, low SO2 oxidation rate and good sulfur and water resistance. The physical and chemical properties and structure of V3M6T and V3M6TZ-30% catalysts were characterized by XRD, TG, BET, SEM, H2-TPR and NH3-TPD. The results showed that the V3M6TZ-30% catalyst doped with ZrO2 had better selective catalytic reduction of NO activity. This was related to its large specific surface area, sufficient surface hydroxyl groups and weak acid sites, uniform particle size, excellent redox properties.
