| Abstract | In this study, a Cu/SAPO-18 catalyst was treated by H-2 reduction, which induced a remarkable enhancement of the low-temperature NH3-SCR activity. Compared with the fresh catalyst, the reduced Cu/SAPO-18 catalyst showed an increase in NOx conversion from 45% to 80% at 175 degrees C, and from 80% to 100% at 200 degrees C, under a GHSV of 200,000 h(-1). The characterization (XRD, XPS and H-2-TPR) and in-situ DRIFTS results confirmed that a large amount of Cu cations (most of which were Cu+ ions) existed on/in Cu/SAPO-18 after the H-2 reduction treatment. The increased Cu+/Cu2+ ratio led to the enhanced low-temperature SCR activity. |
