Abstract

Recent developments on acidity characterization of solid acid catalysts, specifically those invoking 31P solid-state nuclear magnetic resonance (SSNMR) spectroscopy using phosphorus-containing molecules as probes, have been summarized. In particular, various 31P SSNMR approaches using trimethylphosphine, diphosphines, and trialkylphosphine oxides (R3PO) will be introduced, and their practical applications for the characterization of important qualitative and quantitative features, namely, type, distribution, accessibility (location/proximity), concentration (amount), and strength of acid sites in various solid acids, will be illustrated.
