Vanadia-modified Sb–CeO2/TiO2 catalyst for effective removal of NO by NH3

Effect of FeOx and MnOx doping into the CeO2–V2O5/TiO2 nanocomposite on the performance and mechanism in selective catalytic reduction of NOx with NH3

FeO_x–CeO₂–V₂O₅/TiO₂ catalyst showed higher N₂ selectivity and resistance to SO₂ and H₂O than MnO_x–CeO₂–V₂O₅/TiO₂ catalyst due to their different physicochemical properties. The interaction of Fe, Ce and V oxides and reaction mechanism were explored.

A novel Ce–Sb binary oxide catalyst for the selective catalytic reduction of NOx with NH3

The synergetic effect between Sb and Ce not only increases the surface acidity of the catalyst but also enhances the redox property, both of which contribute to improving NH₃-SCR activity.
