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.
