Solid state NMR is crucial in catalysis for several reasons:
1. Structural Elucidation: It provides detailed information about the atomic and molecular structure of catalysts, including the local environment of active sites. 2. Dynamic Processes: It can probe dynamic processes on the catalyst surface, such as adsorption, desorption, and reaction intermediates. 3. Chemical Composition: It helps determine the composition and distribution of different elements within the solid catalyst. 4. Phase Identification: It aids in identifying different phases present in heterogeneous catalysts.
