Abstract

The Pt/Al2O3, Sn/Al2O3catalysts were prepared by the single sol-gel method. The two-stage Sn/Al2O3and Pt/Al2O3catalyst in series for NO reduction with propene were investigated. The coexistance of water vapor enhanced the activity at medium temperature of 300-400oC, and the NO conversion was above 50% at 225 to 500oC even in the presence of water vapor and SO2.
