31P Solid-State NMR Spectroscopy of Adsorbed Phosphorous Probe Molecules: Acidity Characterization of Solid Acid Carbonaceous Materials for Catalytic Applications

  • Bhaskar Garg
Chapter

Abstract

In recent years, solid acid catalysis has evolved as sustainable route or eco-friendly replacement for their homogeneous counterparts in both industrial and academic settings. In this context, the acidity characterization of solid acid catalysts, in particular carbonaceous materials and composites, using phosphorus-31 magic-angle-spinning solid-state nuclear magnetic resonance (31P MAS SSNMR) spectroscopy is significantly influencing the current state-of-the-art at the interface of materials science and analytical chemistry. This book chapter provides a fair insight about 31P MAS SSNMR of adsorbed phosphorous probe molecules being used for the characterization of surface acidic properties of a variety of carbonaceous materials including graphene. In line with this, the catalytic applications of these carbon-based solid acid catalysts have also been discussed appropriately.
