Comparison of the structural properties of isomorphously substituted Fe in mordenite zeolites prepared by different methods.


Fe was introduced in mordenite zeolite by means of ion exchange either in solid or in liquid state. The iron loading (50--200 wt%), iron precursor (FeSO4.7H2O and FeCl3), and mordenite starting material (NH4M, HM, and NaM) were varied during the exchange processes. The Fe species were characterized by N2 adsorption measurements as well as by XRD and M… (More)
