Ferrate(VI)/Periodate System: Synergistic and Rapid Oxidation of Micropollutants via Periodate/Iodate-Modulated Fe(IV)/Fe(V) Intermediates

The presence of organic micropollutants in water sources worldwide has created a need for the development effective and selective oxidation methods complex matrices. This study is first report combination ferrate(VI) (Fe(VI)) periodate (PI) synergistic, rapid, elimination multiple micropollutants. combined system was found to outperform other Fe(VI)/oxidant systems (e.g., H2O2, peroxydisulfate, peroxymonosulfate) rapid decontamination. Scavenging, probing, electron spin resonance experiments showed that high-valent Fe(IV)/Fe(V) intermediates, rather than hydroxyl radicals, superoxide singlet oxygen, iodyl played dominant role process. Further, generation evidenced directly by 57Fe Mössbauer spectroscopic test. Surprisingly, reactivity PI toward Fe(VI) low (0.8223 M-1 s-1) at pH 8.0, implying not acting as an activator. Besides, only iodine sink PI, iodate also enhanced micropollutant abatement oxidation. Further proved and/or might function ligands, causing utilization efficiency intermediates pollutant outcompete their auto-decomposition. Finally, oxidized products plausible transformation pathways three different single Fe(VI)/PI were characterized elucidated. Overall, this proposed novel strategy (i.e., system) could efficiently eliminate clarified unexpected interactions between PI/iodate accelerated

This perspective presents the latest advancements in selective polymerization pathways advanced oxidation processes (AOPs) for removal of featured organic pollutants wastewater. In radical-based homogeneous reactions, SO4• –-based systems exhibit superior oxidative activity toward aromatics with electron-donating substituents via single electron transfer and radical adduct formation (RAF). The produced cations subsequently undergo coupling reactions to produce polymers. For •OH-based oxidation, metal ions facilitate production monomer radicals RAF. Additionally, heterogeneous catalysts can mediate both persulfate activation without generating inorganic radicals. Metal-based will a direct pathway polymerization. contrast, carbon-based induce low-molecular-weight oligomers (≤4 units) an process. comparison mineralization, remarkably reduce peroxide usage, quickly separate from aqueous phase, generate polymeric byproducts. Thus, AOP-driven hold significant promise reducing carbon emission realizing recycling water treatment processes.

Single‐Atom Catalysts Originated from Metal–Organic Frameworks for Sulfate Radical‐Based Advanced Oxidation Processes: Critical Insights into Mechanisms

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(6)

Published: Oct. 22, 2023

Abstract The widely discussed single‐atom catalysts (SACs) are regarded as a kind of attractive material for sulfate radical‐based advanced oxidation processes (SR‐AOPs) owing to their maximum atomic utilization efficiency and outstanding stability. Currently, metal–organic frameworks (MOFs) have appeared prospective precursors building SACs due extensive chelating sites, functional adjustability, structural tunability. However, there few critical systematic reviews about the application MOF‐derived in SR‐AOPs, especially in‐depth analysis mechanisms. Therefore, this review seeks offer thorough summary development SR‐AOPs. First, unique advantages MOFs derivative thoroughly. Afterward, current synthesis strategies elaborated categorically unveil formation process single atoms coordination environments. Notably, roles different reaction sites including generation reactive species mediating electron transfer further analyzed explain mechanisms comprehensively. Thereafter, characterization techniques theoretical calculations studies also highlighted. Eventually, insights into present challenges future developments proposed, which expected enhance catalytic
