How Do Metal Oxides Mislead Spin-Trapping Electron Paramagnetic Resonance Analysis?

Environmental Science & Technology Letters, Год журнала: 2024, Номер 11(4), С. 370 - 375

Опубликована: Март 14, 2024

Limited by the detection techniques, reactive species involved in catalytic water purification processes are difficult to be clarified. Spin-trapping electron paramagnetic resonance (EPR) analysis is recognized as a reliable tool for radical identification, which 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) usually used trapper. However, it questioned that of adducts DMPO definitively indicates generation radicals. In this work, transformation caused transition metal oxides monitored EPR, and abundant spin signals observed. MnO2, Mn2O3, NiO could oxidize into DMPOX through direct oxygen transfer. Besides, dissolved ions transform misleading DMPO–OH DMPO–R. The findings e.g., interactions between different quenching behavior pathways, would help with identifications both engineered systems natural environments.

Advanced oxidation processes (AOPs) are rapidly evolving but still lack well-established protocols for reliably identifying oxidative reactive species (ORSs). This Perspective presents both the radical and nonradical ORSs that have been identified or proposed, along with extensive controversies surrounding mechanisms. Conventional identification tools, such as quenchers, probes, spin trappers, might be inadequate analytical demands of systems in which multiple coexist, often yielding misleading results. Therefore, challenges these complex, short-lived, transient must fully acknowledged. Refining methods is necessary, supported by rigorous experiments innovative paradigms, particularly through kinetic analysis based on situ spectroscopic techniques multiple-probe strategies. To demystify complex ORSs, future efforts should made to develop advanced tools strategies enhance mechanism understanding. In addition, integrating real-world conditions into experimental designs will establish a reliable framework fundamental studies, providing more accurate insights effectively guiding design AOPs.
