Abstract: Potassium has a serious deactivation effect on V/TiO₂ catalyst for selective catalytic reduction of NO with NH₃. It was found that the doping of Cu can not only enhance the K resistance of V/TiO₂ catalyst, but also enhance the low-temperature SCR activity. Based on the characterization results, it can be concluded that the good redox ability and NH₃ adsorption capacity, and the increase of reduced vanadium species and active oxygen species are the main factors for the good performance of V-Cu/TiO₂ catalyst.

Keywords: SCR; V/TiO₂ catalyst; Copper; Potassium; Resistance
