Effects of SiO2 modification on the hydrothermal stability of the V2O5/WO3–TiO2 NH3-SCR catalyst: TiO2 structure and vanadia species

The addition of silica could produce the SixTi1−xO2 solid solutions at the interface in the doped catalyst, which inhibit the direct contact among anatase crystals and improve the stable textural property of V2O5/WO3–TiO2 catalyst.
