英文摘要 | Activity test and in situ DRIFTS experiments were carried out on the selective catalytic reduction of NOx by propene over Ag (5 wt%)-Pd (0.01 wt%)/Al2O3 and Ag (5 wt%)-Pd (0.01 wt%)/Al2O3-SiO2. The activity test results showed that the Ag-Pd/Al2O3SiO2 had a higher NOx conversion than Ag-Pd/Al2O3 in the presence of SO2. The in situ DRIFTS results showed the SO2 poisoned Ag-Pd (0.01 wt%)/Al2O3 surface inhibited the formation of enolic species and NO3-, which are reactive intermediates to form -NCO species. However, the SO2 poisoned Ag-Pd (0.01 wt%)/Al2O3-SiO2 surface can hardly affect the formation of enolic species, NO3 and -NCO species. The reaction mechanism of NOx reduction and the effect of adding SiO2 are discussed based on these results. (C) 2005 Elsevier B.V. All rights reserved. |
