Influence of ceria modification on the properties of TiO2-ZrO2 supported V2O5 catalysts for selective catalytic reduction of NO by NH3

► A quadri-component V2O5-CeO2/TiO2-ZrO2 was prepared and applied in the SCR reaction. ► Such a complex showed a stable and high activity than the tri-component counterpart. ► The Ce-modified catalysts possessed a large amount of Brønsted and Lewis acid sites. ► The addition of CeO2 promoted the formation of active intermediate on the surface.
