Interrogating the Lewis Acidity of Metal Sites in Beta Zeolites with (15)N Pyridine Adsorption Coupled with MAS NMR Spectroscopy
The Lewis acidity of isolated framework metal sites in Beta zeolites was characterized with (15)N isotopically labeled pyridine adsorption coupled with magic-angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy. The (15)N chemical shift of adsorbed pyridine was found to scale with the ac...
