  • A series of V-Mo/TiO2 catalysts were prepared by impregnation method, sol-gel method and hydrothermal method. The denitrification performance and anti-SO2/H2O performance of the catalysts were investigated.The physical and chemical properties of the catalyst were characterized by XRD, BET, NH3-TPD, H2-TPR and XPS.The results showed that the catalyst prepared by sol-gel method had smaller grain size, larger specific area and pore volume, more surface acidity, stronger redox ability and higher V4+ and surface active oxygen.Therefore, the 3% V2O5-6% MoO3/TiO2 (sol-gel) catalyst exhibited the best denitration efficiency in the temperature range of 80-360℃. After introducing 10% H2O and 0.03% SO2, the NO conversion of 3% V2O5-6% MoO3/TiO2 (sol-gel) catalyst decreased by only 7 percentage points, showing the best resistance to SO2/H2O.
