Abstract: Abstract A series of V2O5-WO3/TiO2-ZrO2, V2O5-WO3/TiO2-CeO2, and V2O5-WO3/TiO2-CeO2-ZrO2 catalysts were synthesized to improve the selective catalytic reduction (SCR) performance and the K-poisoning resistance of a V2O5-WO3/TiO2 catalyst. The physicochemical properties were investigated by using XRD,… read more here.
