Singlet oxygen (1O2) plays a pivotal role in numerous catalytic oxidation processes utilized in water purification and chemical synthesis. The spin-trapping method based on electron paramagnetic resonance (EPR) analysis is commonly employed for 1O2 detection. However, it is often limited to time-independent acquisition. Recent studies have raised questions about the reliability of the 1O2 trapper, 2,2,6,6-tetramethylpiperidine (TEMP), in various systems. In this study, we introduce a comprehensive, kinetic examination to monitor the spin-trapping process in EPR analysis. The EPR intensity of the trapping product was used as a quantitative measurement to evaluate the concentration of 1O2 in aqueous systems. This in situ kinetic study was successfully applied to a classical photocatalytic system with exceptional accuracy. Furthermore, we demonstrated the feasibility of our approach in more intricate 1O2-driven catalytic oxidation processes for water decontamination and elucidated the molecular mechanism of direct TEMP oxidation. This method can avoid the false-positive results associated with the conventional 2D 1O2 detection techniques, and provide insights into the reaction mechanisms in 1O2-dominated catalytic oxidation processes. This work underscores the necessity of kinetic studies for spin-trapping EPR analysis, presenting an avenue for a comprehensive exploration of the mechanisms governing catalytic oxidation processes. 1 O 2 is a vital species for the selective oxidations of chemicals. However, detecting its production and understanding the underlying mechanisms in complex systems remains challenging. The spin-trapping method based on EPR (electron paramagnetic resonance) analysis has emerged as an indispensable tool for identifying the generation of 1 O 2 . Here, we applied EPR analysis to track the fates of 1 O 2 in catalytic oxidation processes, offering time-dependent profiles of trapping products. These detailed examinations can unveil the molecular mechanism of direct 2,2,6,6-tetramethylpiperidine oxidation and mitigate the risk of false positives. This study paves the way for exploring 1 O 2 generation in aqueous solutions and catalytic oxidations governed by other oxidative species and also offers thorough clarification from the mechanism of spin-trapping to its application scenarios.
