Cu-SAPO-34 and CuY-SAPO-34 catalysts for NH3-SCR were prepared by the wet-impregnation method. XRD, UV-vis DRS, ESR and NH3-TPD results showed that the introduction of Y effectively improved the dispersion of copper species, increased the amount of isolated copper ions and enhanced the acid density. In addition, the activity test, NH3-TPD and TGA results reflected that the CuY-SAPO-34 catalyst showed better C3H6 oxidation activity, lower dropping degree of acid sites after C3H6/O2 treatment and less adsorption of C3H6/O2 than Cu-SAPO-34 catalyst. Therefore, the addition of Y promoted the NH3-SCR performance and the hydrocarbon (HC) resistance of Cu-SAPO-34 catalyst.
