Abstract
The NO oxidations kinetics on iron exchanged zeolites with FER, MFI, and *BEA framework was studied. The kinetic analysis revealed the occurrence of strong reaction inhibition by adsorbed NO2. FER and MFI zeolites were more active than *BEA type zeolite. MFI zeolite was most active but suffered most from NO2 inhibition of the reaction rate. The presence of Fe3+ ions in cationic sites was essential for the oxidation of NO into NO2. Compared to the isolated Fe3+ species, the binuclear complexes abundantly present in the MFI zeolite was the most sensitive to poisoning by NO2.
