Variations in bonding of iron in porous ferrisilicates

Research output: Contribution to journalArticle

Abstract

Bonding strengths of iron species in different micro- and mesoporous ferrisilicates are deduced from analysis of changes in recoilless fractions extracted from various series of in situ spectra. The recoilless fractions for extra-framework ions in microporous Fe-LTA may depend strongly on the conditions. In Fe-FER, containing both framework and extra-framework types of iron, modest changes were detected. In mesoporous Fe-MCM-41 samples variations of the bonding strengths were revealed which can apparently be correlated with the partly amorphous structure of the pore walls in these substances.
