Structure and reactivity of framework and extraframework iron in Fe-silicalite as investigated by spectroscopic and physicochemical methods
- Universita di Torino (Italy); and others
The application of IR, Raman, UV-visible, EPR, XANES, EXAFS, and TPR techniques to the determination of the Fe{sup 3+} local environment in Fe-silicalite is described and discussed. These methods give information concerning the structural changes of the zeolitic structure, upon thermal treatments and interaction with adsorbates. In particular the effect of template burning at 773 K or at 973 K on the local Fe{sup 3+} environment has been discussed in detail. The reactivity of the zeolite towards NH{sub 3} has also been discussed. 64 refs., 11 figs., 3 tabs.
