| 英文摘要 | Herein, we report the performance of the catalytic oxidizing, trapping and releasing NO over the MnOx (Mn2O3, Mn3O4 and MnO2) model Lean NOx Traps (LNT) catalysts at low temperatures (<= 200 degrees C). Among these typical MnOx samples, Mn2O3 has the high NO oxidizability, and can efficiently trap and release NOx in the alternative lean-burn/fuel-rich atmospheres. Our characterization results show that enrichment of the Mn3+ cations and active surface oxygen species probably plays the important role for NO oxidation. Although MnO2 has the biggest NOx storage capacity in the lean-burn atmosphere, the strong adsorption strength between MnO2 and NOx inhibits the release of the stored NOx species in the fuel-rich atmosphere. The in situ DRIFTS and NO-TPD studies indicate that the trapped NOx on Mn2O3 can transform from nitro compounds to nitrites, and then to nitrates along with the increased adsorption temperature. |
