High NH3-SCR reaction rate with low dependence on O2 partial pressure over Al-rich Cu-*BEA zeolite

Dependence of NH3-SCR reaction rate on O-2 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 O-2 partial pressure.
