Original Paper


The influence of hydrogen and silver loading on lean NOx reduction with methanol over Ag–Al2O3 are investigated by flow-reactor experiments, H2-TPR, TEM and XPS. Reduction of silver at low temperatures over Ag–Al2O3 with high silver loading, suggests involvement of silver species/particles that are large (which is supported by the TEM analysis) and/or loosely bound to the support. The silver species reduced by hydrogen cannot be directly associated with the activity for NOx reduction under methanol-SCR conditions. Furthermore, the activity for NOx reduction increases slightly at low temperatures when hydrogen is added to the feed. However, also without co-fed hydrogen, a high low-temperature activity is achieved for methanol assisted lean NOx reduction over Ag–Al2O3.
