| Abstract: | Ag/Al2O3 catalysts (2 wt% Ag) have been prepared and calcined at different temperatures to render catalysts with different silver
particle size or silver configuration. The differences in activity and selectivity of these catalysts are related to the activity
for oxidation of NO and hydrocarbons, the NOx storage properties, and to the oxidation state of silver. |
