Chapter Four - Structural Characterization of Zeolites by Advanced Solid State NMR Spectroscopic Methods

This review overviews the application of solid state NMR spectroscopy to the structural characterization of silicate, and acidic aluminosilicate and borosilicate zeolites focusing on the utilization of new developed methods. We summarize recent results on the investigations of the distribution of silicon atoms into the zeolite framework, as well as the location of F− anions and formation of pentacoordinated silicon species in zeolites synthesized in fluoride medium. Special attention is paid here to the characterization of framework and extraframework boron and most specially aluminium species and the acid sites in zeolites. In Section 6 of this review, we present the basis and practical aspects of advanced NMR experiments used in the characterization of microporous solids paying special attention to quadrupolar nuclei and other methods based on dipolar interactions.
