S. Bordiga et al., STRUCTURE AND REACTIVITY OF FRAMEWORK AND EXTRAFRAMEWORK IRON IN FE-SILICALITE AS INVESTIGATED BY SPECTROSCOPIC AND PHYSICOCHEMICAL METHODS, Journal of catalysis, 158(2), 1996, pp. 486-501
The application of LR, Raman, UV-visible, EPR, XANES, EXAFS, and TPR t
echniques to the determination of the Fe3+ local environment in Fe-sil
icalite is described and discussed. These methods give information con
cerning 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 Fe3+ environment
has been discussed in detail. The reactivity of the zeolite towards N
H3 has also been considered. (C) 1996 Academic Press, Inc.
