Advanced oxidation processes (AOPs) can degrade a wide range of trace organic contaminants (TrOCs) to improve the quality potable water or discharged wastewater effluents. Their effectiveness is impacted, however, by dissolved matter (DOM) that ubiquitous in all sources. During application an AOP, DOM scavenge radicals and/or block light penetration, therefore impacting their toward contaminant transformation. The multiple ways which different types sources impact oxidative purification are critically reviewed. inhibit degradation TrOCs, but it also enhance formation and reactivity useful for elimination alter transformation pathways contaminants. An in-depth analysis highlights inhibitory effect on efficiency TrOCs based DOM's structure optical properties its oxidants as well synergistic contribution from redox transient intermediates. AOPs influence types, mechanisms, extent byproducts formation. Research needs proposed advance practical understanding how be exploited purification.

Abstract Polymeric g‐C 3 N 4 is a promising visible‐light‐responsive photocatalyst; however, the fast recombination of charge carriers and moderate oxidation ability remarkably restrict its photocatalytic efficiency towards organic pollutants. To overcome these drawbacks, self‐modification strategy one‐step formaldehyde‐assisted thermal polycondensation molten urea to prepare carbon‐deficient oxygen‐doped (V C ‐OCN) developed, carbon vacancy concentration well‐controlled by changing formaldehyde dosage. The V ‐OCN catalysts exhibit interesting concentration‐dependent removal p ‐nitrophenol (PNP) atrazine (ATN), in which 15 with appropriate displays significantly higher pollutant than bulk . apparent first‐order rate constant for PNP ATN 4.4 5.2 times that A combination experimental results theoretic calculations confirm synergetic effect vacancies oxygen doping sites can not only delay but also facilitate adsorption molecules on vacancies, leads generation plentiful active species including superoxide anion radicals indirectly formed hydroxyl singlet oxygen.

Photocatalytic Advanced Oxidation Processes for Water Treatment: Recent Advances and Perspective

Chemistry - An Asian Journal, Год журнала: 2020, Номер 15(20), С. 3239 - 3253

Опубликована: Авг. 29, 2020

Nowadays, an ever-increasing variety of organic contaminants in water has caused hazards to the ecological environment and human health. Many them are persistent non-biodegradable. Various techniques have been studied for sewage treatment, including biological, physical chemical methods. Photocatalytic advanced oxidation processes (AOPs) received increasing attention due their fast reaction rates strong capability, low cost compared with non-photolytic AOPs. This review is dedicated summarizing up-to-date research progress photocatalytic AOPs, such as Fenton or Fenton-like reaction, ozonation sulfate radical-based processes. Mechanisms activation discussed. Then, paper summarizes materials modification strategies, defect chemistry, morphology control, heterostructure design, noble metal deposition. The future perspectives challenges also
