Abstract

To meet more strict international Europe VI emission standard, Cu–Ce/SAPO-34 and Cu–Ce/SSZ-13 were prepared by once ion exchange–impregnation methods for the selective catalytic reduction (SCR) of NOx with NH3, and physicochemical properties as well as its catalytic characteristics had been investigated. Comparing to the Cu–Ce/SAPO-34 catalyst, Cu–Ce/SSZ-13 catalyst showed better low-temperature activity, wider temperature window, excellent resistance to H2O and SO2, good dispersion, low reduce temperature, and the strongest surface acidity. Cu–Ce/SSZ-13 catalyst was a promising technology for De–NOx with NH3 in diesel vehicle.
