For several decades, the methodology of complete destruction organic pollutants via oxidation, i.e., mineralization, has been rooted in real water treatment applications. Nevertheless, this industrially accepted protocol is far from sustainable because excessive input chemicals and/or energy as well unregulated carbon emission. Recently, there have emerging studies on removal a completely different pathway, polymerization, meaning that target undergo oxidative polymerization reactions to generate polymeric products. These collectively shown compared conventional mineralization pathway allows more efficient pollutants, largely reduced chemicals, and suppressed In review, we aim provide comprehensive examination fundamentals process, current state-of-the-art strategies for regulation both kinetic thermodynamic perspectives, resource recovery formed end, limitations process pollutant are discussed, with perspectives future studies. Hopefully, review could not only critical insight advancement polymerization-oriented technologies greener manner but also stimulate paradigm innovations low-carbon treatment.

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

Опубликована: Окт. 9, 2024

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.

Controllable Supply–Demand Effect during Superior Fe Single-Atom Catalyst Synthesis for Targeted Guanine Oxidation of Antibiotic Resistance Genes

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Март 6, 2025

Nonradical Fenton-like catalysis offers an opportunity to degrade extracellular antibiotic resistance genes (eARGs). However, high-loading single-atom catalysts (SACs) with controllable configurations are urgently required selectively generate high-yield nonradicals. Herein, we constructed Fe SACs (5.4-34.2 wt %) uniform Fe-N4 sites via optimized coordination balance of supermolecular assembly for peroxymonosulfate activation. The selectivity singlet oxygen (1O2) generation and its contribution eARGs degradation were both >98%. This targeting strategy oxidizing guanines low ionization potentials by 1O2 allowed 7 log within 10 min eliminated their transformation 2 min, outperforming most reported advanced oxidation processes. Relevant interactions between revealed at a single-molecule resolution. exhibited excellent universality stability different water matrices. These findings provide promising route constructing efficient selective treatment.
