In situ analysis is essential for several reasons. Firstly, catalysts often undergo significant structural and chemical changes during reactions. Observing these changes in real-time helps in understanding the actual working state of the catalyst. Secondly, it aids in identifying intermediate species and reaction pathways, which can be critical for improving catalytic performance and developing new catalysts. Lastly, in situ techniques can help in diagnosing catalyst deactivation mechanisms, thereby providing strategies for enhancing catalyst longevity.
