Non-intrusive techniques are essential for several reasons: 1. Preservation of Reaction Conditions: They ensure that the reaction conditions remain unchanged during analysis, providing accurate and reliable data. 2. Real-Time Analysis: Many non-intrusive methods allow for real-time monitoring of reactions, enabling the observation of transient states and intermediate species. 3. Enhanced Understanding: These techniques provide detailed insights into the reaction mechanisms, kinetics, and catalytic behavior, which are critical for catalyst development and optimization.
