| dc.description.abstract | Thermal aging effect on NSR kinetics was studied over Pt/Co/Fe/Ba/Al2O3 catalyst. The amount of NOx uptake over Pt/Co/Ba/Al2O3 calcined at 400℃ increased with increasing NSR temperature from 200℃ to 400℃, where amount of NOx uptake is the highest at 400℃ with mol ratio of NOx/Ba = 0.5. Thereafter, the amount of NOx uptake at 400℃ decreased with the higher calcination temperature, where Pt/Co/Ba/Al2O3 catalyst calcined at 700℃ showed an amount of NOx uptake with the mol ratio of NOx/Ba=0.062. Result of XRD and NSR showed that Fe addition into Pt/Co/Ba/Al2O3 suppressed sintering of Pt crystallites and make NOx uptake larger, compared to no addition of Fe into Pt/Co/Ba/Al2O3 catalyst. From BET result, it was found that the change of specific surface area was relatively small by the thermal aging process. Therefore, it was found that the sintering of Pt crystallites caused the decrease of NOx uptake during NSR reaction and Fe played a role to suppress the sintering process of Pt crystallites caused by thermal aging. | - |
