| 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. |
