Tailoring of Fe-ferrierite for N2O decomposition: On the decisive role of framework Al distribution for catalytic activity of Fe species in Fe-ferrierite
Original language description
Two parent ferrierites with similar Si/Al ratio (8.5 and 10.5), a commercial and a laboratory specimen with different distribution of Al atoms in the framework, were used for the preparation of model Fe-ferrierite catalysts for N2O decomposition. As proven by UV?Vis analysis of the fully exchanged Co(II)-ferrierites, the two ferrierites differ in the distribution of framework Al between Al?O?(Si?O)2?Al sequences in one ring (Al pairs) and single Al atoms in different rings (Al?O?(Si?O)n>2?Al sequences).The part of the framework Al atoms arranged in Al pairs mostly in ? six-member rings was 66% and 30% of Al for the two ferrierites. Two series of Fe-ferrierites with low concentration between 0.4 and 2.1 wt.% Fe were prepared, containing Fe ions in cationic sites, and valence and siting analyzed by Mössbauer spectroscopy of 57Fe isotope enriched (96%) samples.
