Confronting the Mysteries of Oxidative Reactive Species in Advanced Oxidation Processes: An Elephant in the Room

Environmental Science & Technology, Год журнала: 2024, Номер 58(42), С. 18496 - 18507

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.

Surface-hydroxylated single-atom catalyst with an isolated Co-O-Zn configuration achieves high selectivity in regulating active species

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 11, 2025

Single-atom catalysts (SACs) are emerging as potent tools for the selective regulation of active species, offering substantial promise green and sustainable Fenton catalysis. However, current SACs face limitations due to specificity their supports, which only allow within certain oxidant systems. This constraint makes targeted across different systems challenging. In response, this study designs a SAC, termed CoSAs-ZnO, featuring surface hydroxylation an isolated asymmetric Co-O-Zn configuration. SAC can realize nearly 100% generation sulfate radicals (SO4•−) singlet oxygen (1O2) in peroxymonosulfate (PMS) peracetic acid (PAA) systems, respectively. Moreover, PMS-activated system efficiently treat electron-deficient-dominated refractory benzoic wastewater, achieving 100.0% removal multiple consecutive pilot-scale experiments. The PAA-activated facilitates rapid conversion benzyl alcohol benzaldehyde, with high selectivity 89.0%. Detailed DFT calculations reveal that hydroxyl groups on ZnO play critical role modulating adsorption configurations oxidants, thus enabling specific species each system. provides insights into design multifunctional applications paves way deployment wastewater treatment high-value chemical conversion. supports.
