Review of the application of Cu-containing SSZ-13 in NH(3)-SCR-DeNO(x) and NH(3)-SCO

The reduction of NO(x) emissions has become one of the most important subjects in environmental protection. Cu-containing SSZ-13 is currently the state-of-the-art catalyst for the selective catalytic reduction of NO(x) with ammonia (NH(3)-SCR-DeNO(x)). Although the current-generation catalysts reveal enhanced activity and remarkable hydrothermal stability, still open challenges appear. Thus, this review focuses on the progress of Cu-containing SSZ-13 regarding preparation methods, hydrothermal resistance and poisoning as well as reaction mechanisms in NH(3)-SCR-DeNO(x). Remarkably, the paper reviews also the progress of Cu-containing SSZ-13 in the selective ammonia oxidation into nitrogen and water vapor (NH(3)-SCO). The dynamics in the NH(3)-SCR-DeNO(x) and NH(3)-SCO fields make this review timely.
