Adsorbate-induced frustrated Lewis pairs as catalytic active sites in zeolite

Zeolites are highly important heterogeneous catalysts and have been widely applied in many industrial reactions. The properties of active sites strongly dictate the catalytic behaviors of zeolite catalysts. The classic active sites for adsorption or catalysis on zeolite surfaces, such as the Brønsted acid site (BAS) and Lewis acid site (LAS), are generally believed to locate at the fixed crystallographic positions. However, some recent observations indicate that the framework of zeolites is not a static structure during catalytic reactions. Neutron powder diffraction of organic probe adsorbed zeolites will enable us to understand the structure change of active sites. This can be achieved by studying H+(D+) of zeolites locations, the adsorption geometry of probe (acetone, methanol, ethanol, etc) locations in zeolites.
