Abstract

Siting of iron and its ability to take part in the Fe3+ ↔ Fe2+ redox process are correlated in certain micro-and mesoporous ferrisilicates as deduced from changes in coordination and oxidation states of iron followed from in situ Mössbauer spectroscopy. The three-dimensional crystalline character stabilizes the Fe3+ state in microporous framework sites, whereas the mentioned reversible redox process proceeds more easily on extra-framework sites in microporous systems, as well as on iron located in the pore walls of the mesoporous ferrisilicates. Correlations with catalytic properties are also mentioned in certain instances.
