Mossbauer investigation of Fe 57 in Linde L Zeolite

Two independent Fe³⁺ species have been simultaneously introduced into Linde L zeolite. One is an exchanged Fe³⁺ species while the other
is the molecular species FeCI₃, By simpIe outgassing at 573°K, the
exchanged Fe³⁺ is reduced to Fe²⁺. By sweeping the system at 523°K with
H₂, both species are converted to ferrous and, at 573°K, the exchanged species is reduced to Feº and the FeCI₃ is reduced to FeCI₂. Outgassing the latter system at 573°K oxidizes the Feº to Fe₂O₃ while the FeCI₂ remains intact. These valency changes were examined using Mössbauer Spectroscopy and, using this technique, a Morin transition appears to have been detected in the Feº species. / Science, Faculty of / Chemistry, Department of / Graduate
