摘要
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.
