Acidity and Basicity of Solid Acid Catalysts Studied by Solid-State NMR

Abstract

Solid-state nuclear magnetic resonance (NMR) is an important technique to study the acidity and basicity of solid catalysts. Here we review some research works carried out in our laboratory, including studies on the acidity of metal oxides under different water contents, the acidity and basicity characterization of metal oxides by using acidic and basic probe molecules simultaneously. The investigations extend solid-state NMR technique in qualitative and quantitative studies on the acidity and basicity of solid catalysts.
