Abstract

Dependence of NH₃-SCR reaction rate on O₂ partial pressure was investigated at 473 K over Cu ion-exchanged MOR, MFI, CHA and *BEA zeolites with varying "Cu density in micropores". Among the zeolites, Cu-*BEA zeolite demonstrated promising potential as an effective catalyst for NH₃-SCR over a wide range of O₂ partial pressure.
