    AnotaceIron ferrierites with low iron content (Fe/Al between 0.018 and 0.072) were used as model catalysts to evaluate the participation of individual iron species, with special interest in the role of iron in β cationic sites, for formation of active sites for N2O decomposition. Despite low iron content, the catalysts with prevailing iron located in β sites of two types exhibited high conversions of N2O and activity increase with increase of iron loading. These results indicate formation of the active iron species already at very low concentrations, while at higher concentration level would part of the iron enter also into less active positions. Semi-quantitative analysis of the TOF values of individual iron centers was done using the recently established Mössbauer parameters of the Fe(II) parameters for individual iron cationic species, i.e. β (β-1 and β-2) and α sites [1].
