Solid-state NMR is particularly valuable for studying heterogeneous catalysts, such as those used in industrial processes. Techniques like Magic Angle Spinning (MAS) and Cross Polarization (CP) enhance the resolution and sensitivity of solid-state NMR. These methods allow researchers to examine the surface interactions, active sites, and support materials of solid catalysts. Solid-state NMR can also provide information on the distribution and dynamics of adsorbed species on the catalyst surface.
