英文摘要	Solid-state nuclear magnetic resonance (NMR) is a well-established tool for the structural characterization and dynamics study of various multifunctional materials. This review intends to cover the recent process for versatile solid-state NMR studies of topology structures, crystallization processes, host-guest interactions, acidities and catalytic reaction mechanisms of various zeolites. New insights into the relationship between zeolite structures and properties at the atomic level could benefit a lot from the new developments of solid-state NMR methodology and density functional theoretical (DFT) calculation. The spatial connections, distance information and anisotropic chemical shifts of silicon sites determined by Si-29 magic angle spinning (MAS) NMR can serve as structural constraints to resolve the topology structure of zeolites. Xe-129 NMR can be employed to investigate the cage and channel structure and communication in zeolites. The host-guest interactions between zeolite frameworks and confined molecules have been characterized by two-dimensional heteronuclear correlation experiments. The acidity property of zeolites (including acid type, strength, concentration as well as distribution) can be well understood through the combination of solid-state NMR probe molecule technique and DFT calculation. In particular, information about spatial proximities among various acid sites in zeolites is available from two-dimensional double quantum MAS NMR experiments. The crystallization and catalytic reaction mechanisms can be elucidated by monitoring the evolution of crystallization and reaction processes, respectively, through solid-state NMR spectroscopy.
