Abstract:

Zeolites have the desired advantages of tunable acidity and shape selectivity for their outstanding performance in heterogeneous catalysis. This review focuses on the recent progress in the understanding of acidity and shape-selectivity in zeolites by solid-state nuclear magnetic resonance(ssNMR) spectroscopy. The number, strength, type, and synergistic effect of the acid sites in zeolites have been explored by ssNMR with/without probe molecules. Moreover, ssNMR investigations provide evidence of the shape-selectivity of zeolites by the direct observation of crucial intermediates in heterogeneous reactions. The synergy of the acidity and shape-selectivity helps the better design of the zeolites for better heterogeneous catalysis.

Key words: Acidity, Shape selectivity, Zeolites, Solid-state NMR, Synergistic effect
