DRIFTS can provide a wealth of information about catalytic systems, including: 1. Identification of Surface Species: By analyzing the IR spectra, researchers can identify the chemical species adsorbed on the catalyst surface. 2. Reaction Intermediates: It helps in detecting and characterizing reaction intermediates, providing insights into the reaction pathway. 3. Active Sites: DRIFTS can help identify and characterize the active sites on a catalyst, which are crucial for catalytic activity. 4. Mechanistic Insights: By monitoring changes in the IR spectra during a reaction, researchers can gain a better understanding of the reaction mechanism and kinetics.
