1. Zeolites: Zeolites are microporous aluminosilicate minerals often used as catalysts in petrochemical industries. 29Si NMR can identify different silicon environments, which helps in understanding the acid sites and framework structure. 2. Silica-supported Catalysts: These are widely used in industrial processes. 29Si NMR can help in characterizing the surface silanol groups and their interaction with the metal sites. 3. Organosilicon Compounds: These are used in various catalytic transformations. 29Si NMR aids in understanding the reaction mechanisms and the stability of these compounds.
