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 , physic-chemical 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 H2 O and SO2 , good dispersion, low reduce tempera- ture and the strongest surface acidity.Cu-Ce/SSZ-13 catalysts was a promising technology for De-NOx with NH3 in disel vehicle.
