Abstract : Mossbauer spectroscopic studies have provided a reasonably consistent picture of the structure and chemistry of iron exchanged Y zeolite. It has been demonstrated that the oxidation-reduction behavior of ferric and ferrous exchanged Y Zeolite is related and that the same chemical states of iron are formed in both materials. The reversible oxidation of the zeolite iron ions by oxygen adsorption may have important implications for catalytic oxidation. The exchange of iron ions into zeolites with different structures and silicon to aluminum ratios and the observations of reversible oxidation may allow the preparation of oxidation catalysts with unique properties and selectivity.
