Abstract:

Due to their excellent catalytic performances in the conversion of biomass molecules such as glucose and lactic acid, the Sn-containing zeolite catalysts have received wide attention. Understanding detailed structures and acidity properties of the active sites and the corresponding catalytic reaction mechanisms is a critical step in developing fundamental insights into the catalytic function and exploiting more highly active zeolite catalysts. Solid-state nuclear magnetic resonance (NMR) spectroscopy provides useful information on the local structures and acidity properties of active centers, as well as the catalytic reaction mechanisms in zeolites. This review briefly introduces the application of solid-state NMR technique in the studies on Sn-containing zeolites. Further challenges and perspectives are also discussed.

Key words: solid-state nuclear magnetic resonance (NMR), Sn-zeolite, active center, acidity, reaction mechanism
