Improved Low- and High-temperature NH3-SCR Activity over Cu-CHA Prepared by Solid-state Ion-exchange Facilitated by NH3 and NO
Paper in proceedings, 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.
