Abstract
Solid-state NMR (ssNMR) spectroscopy is a powerful technique for characterizing the surface sites of solid acids and organic intermediates formed during the acid catalyzed reaction. As a very useful probe molecule, ammonia is often utilized to determine the density of solidacids’ surface sites by ssNMR spectroscopy. The present mini-review summarizes some of the latest research developments on the quantitative characterization of the acid sites and carbenium ions during the zeolite catalytic reaction by ammonia probe-assisted ssNMR spectroscopy.
