Improved Low- and High-temperature NH3-SCR Activity over Cu-CHA Prepared by Solid-state Ion-exchange Facilitated by NH3 and NO
Paper i proceeding, 2015

This presentation will focus on optimizing the copper oxide concentration used in the physical mixture Before treatment. Furthermore, we are showing that Cu-CHA prepared by [NO+NH3]-SSIE can possess relatively high activity both for low- and high-temperature NH3-SCR compared to Cu-CHA prepared by conventional aqueous-based ion-exchange, even by using lower copper content. The study shows that the 2.0% Cu-CHA sample prepared by the [NO+NH3]-SSIE method possesses the highest NH3-SCR activity among the studied catalysts.
