Organic pollutants are harmful to the environment due their bio-accumulative and long-persistent nature, causing adverse effects on plants, animals, humans. Their rapid spread beyond target applications in ecosystem could be responsible for various fatal diseases eco imbalances. Conventional techniques removing these ineffective because of high solubility water nonbiodegradability. In contemporary times, we have witnessed a notable surge interest advanced oxidation processes (AOPs) treatment processes. This heightened attention is attributed exceptional degradation efficiency recalcitrant organic pollutants. review, therefore, focuses copper-based homogeneous heterogeneous catalysts AOPs that offer both cost-effectiveness performance. Emphasis placed use photocatalysis, Fenton-like process (including photo-Fenton (Fe2+/UV/H2O2)), persulfates activation, ultrasonic irradiation. The catalytic performance, mechanism, pathway abatement by each AOP described detail. reusability, stability, factors affecting briefly highlighted. We further provide perspectives key opportunities challenges associated with AOPs, recommending exploration enhanced future studies.

Low-peroxide-consumption Fenton-like Systems: The future of advanced oxidation processes

Water Research, Год журнала: 2024, Номер 268, С. 122621 - 122621

Опубликована: Окт. 11, 2024

Conventional heterogeneous Fenton-like systems employing different peroxides have been developed for water/wastewater remediation. However, a large population of consumed during various with low utilization efficiency and associated secondary contamination become the bottlenecks their actual applications. Recent strategies lowering peroxide consumptions to develop economic are primarily devoted effective radical generation subsequent high-efficiency through catalysts/systems engineering, leveraging emerging nonradical oxidation pathways higher selectivity longer life reactive intermediate, as well reactor designs promoting mass transfer decomposition improve yield radicals/nonradicals. comparative review summarizing mechanisms these has not yet published. In this review, we endeavor showcase designated achieving reduction while ensuring high catalytic activity from perspective above strategic mechanisms. An in-depth understanding aspects will help elucidate key consumption. Finally, existing problems put forward, new ideas research directions consumption proposed promote application in wastewater purification.
