Gambling of homogeneous and heterogeneous Fenton in wastewater treatment

Cell Reports Physical Science, Год журнала: 2024, Номер 5(5), С. 101966 - 101966

Опубликована: Май 1, 2024

Employing Fenton technology for efficiently removing pollutants in water stands as a significant method. Within the domain of traditional techniques, there exist both homogeneous and heterogeneous systems. Homogeneous systems tackle iron sludge concerns through incorporation co-catalysts, whereas adeptly manipulate surface microenvironments adjust active sites, enabling pollutant degradation across wide range pH. Each system boasts distinct advantages limitations. This perspective critically examines existing challenges associated solutions reactions comprehensive analysis typical case studies. The focus is on evaluating industrial potential these systems, forecasting future developmental trends, fostering more robust sustainable advancement within context carbon peaking neutrality goals.

Active Center Size-Dependent Fenton-Like Chemistry for Sustainable Water Decontamination

Environmental Science & Technology, Год журнала: 2023, Номер 57(50), С. 21416 - 21427

Accurately controlling catalytic activity and mechanism as well identifying structure–activity–selectivity correlations in Fenton-like chemistry is essential for designing high-performance catalysts sustainable water decontamination. Herein, active center size-dependent with single cobalt atoms (CoSA), atomic clusters (CoAC), nanoparticles (CoNP) were fabricated to realize the changeover of peroxymonosulfate (PMS)-based chemistry. Catalytic durability vary change metal sizes. Besides, reducing size from significantly modulates contributions radical nonradical mechanisms, thus achieving selective/nonselective degradation. Density functional theory calculations reveal evolutions mechanisms systems over different Gibbs free energies reactive oxygen species generation. Single-atom site contact PMS preferred induce while dissociates generates radicals on nanoparticles. Differences originating reaction endow developed selectivity mineralization treating actual hospital wastewater column reactors. This work brings an in-depth understanding effects guides design intelligent fulfill demand specific scenes purification.
