中文摘要	A series of Fe exchanged zeolites (MOR, USY, BEA and ZSM-5) were prepared by wet ion exchange and tested for N2O catalytic reduction by NH3. Fe-MOR exhibits the highest activity and this is attributed to its highest content of isolated Fe3+ ions and little Fe(III)(x)O-y clusters, since isolated Fe3+ ions are the active species for N2O reduction while Fe(III)(x)O-y clusters inhibit N2O dissociation due to strong NH3 adsorption. Moreover. Fe-MOR not only achieved N2O and NO simultaneously reduction at a very low temperature (700 K) but also showed good durability under simulated conditions at a typical nitric acid plant.
