摘要

A series of Fe exchanged zeolites (MOR, USY, BEA and ZSM-5) were prepared by wet ion exchange and tested for N ₂O catalytic reduction by NH ₃. Fe-MOR exhibits the highest activity and this is attributed to its highest content of isolated Fe ³⁺ ions and little Fe(III) _xO _y clusters, since isolated Fe ³⁺ ions are the active species for N ₂O reduction while Fe(III) _xO _y clusters inhibit N ₂O dissociation due to strong NH ₃ adsorption. Moreover, Fe-MOR not only achieved N ₂O 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.
