What Are Some Common NMR Techniques Used in Catalysis?
Several specialized NMR techniques are particularly useful in catalysis research:
- Solid-State NMR: This technique is essential for studying heterogeneous catalysts, such as zeolites and supported metal catalysts, providing detailed structural information about the active sites. - In Situ NMR: This approach allows the observation of catalytic reactions as they occur, under actual reaction conditions (temperature, pressure, etc.), providing real-time insights. - Dynamic Nuclear Polarization (DNP): Enhances the sensitivity of NMR, making it possible to detect low-concentration species and intermediates that would otherwise be invisible.
