Decomposition of Fe/sub 3/(CO)/sub 12/ on a series of mordenites was studied by magnetic measurements and Mossbauer spectroscopy. Particle size determination for these Fischer-Tropsch catalysts indicated that the best dispersion can be obtained when the number of acid sites in mordenite is maximum. Thermomagnetic measurements and Mossbauer spectroscopy suggested that some iron clusters are inside the pores of mordenites. The change in the Mossbauer isomer shift for Fe/mordenites elucidated the nature of metal-support interactions.
