Abstract As an advanced oxidation process that can efficiently remove organic pollutants in water, Fenton has attracted much attention recent years. Compared to homogeneous Fenton, it a wider applicability, wide pH range, higher degradation efficiency, lower environmental impact, and treatment cost. However, the heterogeneous reaction also some limitations, such as deactivation of catalyst, rate being limited by solid–liquid interface mass transfer. Therefore, development efficient stable catalytic system is focus research at present. In this paper, catalysis are introduced, construction characteristics mechanism iron base, copper transition metals their oxides, chelating agents, carbon materials, supported catalysts, photocatalysis systematically summarized. addition, strategies for formation Fe II promotion H 2 O decomposition were discussed, pathway catalyst matter summarized order provide technical support further on catalysts.

Single-atom catalysts (SACs) are emerging as potent tools for the selective regulation of active species, offering substantial promise green and sustainable Fenton catalysis. However, current SACs face limitations due to specificity their supports, which only allow within certain oxidant systems. This constraint makes targeted across different systems challenging. In response, this study designs a SAC, termed CoSAs-ZnO, featuring surface hydroxylation an isolated asymmetric Co-O-Zn configuration. SAC can realize nearly 100% generation sulfate radicals (SO4•−) singlet oxygen (1O2) in peroxymonosulfate (PMS) peracetic acid (PAA) systems, respectively. Moreover, PMS-activated system efficiently treat electron-deficient-dominated refractory benzoic wastewater, achieving 100.0% removal multiple consecutive pilot-scale experiments. The PAA-activated facilitates rapid conversion benzyl alcohol benzaldehyde, with high selectivity 89.0%. Detailed DFT calculations reveal that hydroxyl groups on ZnO play critical role modulating adsorption configurations oxidants, thus enabling specific species each system. provides insights into design multifunctional applications paves way deployment wastewater treatment high-value chemical conversion. supports.

Abstract The applications of natural laccases are greatly restricted because their drawbacks like poor biostability, high costs, and low recovery efficiency. M/NC single atom nanozymes (M/NC SAzymes) presenting as great substitutes due to superior enzyme‐like activity, excellent selectivity stability. In this work, inspired by the catalytic active center enzyme, a biomimetic Fe/NC SAzyme (Fe‐SAzyme) with O 2 ‐Fe‐N 4 coordination is successfully developed, exhibiting laccase‐like activity. Compared counterpart, Fe‐SAzyme has shown efficiency stability under wide range pH (3.0–9.0), temperature (4–80 °C) NaCl strength (0–300 m ). Interestingly, density functional theory (DFT) calculations reveal that performance attributed activation sites, which weakened O─O bonds in oxygen‐to‐water oxidation pathway. Furthermore, applied for efficient aflatoxin B 1 removal based on its robust This work provides strategy rational design SAzymes, proposed mechanism will help understand environment effect SAzymes processes.

Abstract Zeolite imidazole‐based framework (ZIF‐67), a notable class of metal–organic frameworks (MOFs), shows promise in activating peroxymonosulfate (PMS) for pollutant degradation due to its uniformly distributed cobalt ions. However, nanoparticle form and the elution ions during use cause challenges recycling risk secondary pollution. In this study, magnetic core‐shell hydrogen‐bonded organic (HOF) on MOF (HOF‐on‐Fe 3 O 4 /ZIF‐67) is successfully prepared. The porous HOF shell not only protects active sites mitigates ion leaching but also reduces mass transfer limitations, ensuring sustained catalytic performance. Fe core enhances electron between ions, boosts efficiency, facilitates easy separation recycling. This structure effectively activates PMS, achieving 100% removal Rhodamine B, model wastewater dye, within 10 min (Rh B = 50 mg L −1 , HFZ 150 PMS 1.5 m pH 7, room temperature). Furthermore, under protection shell, minimized negligible value (0.14 ) after 5 cycles use. research provides fresh perspectives into development composite materials with improved performance recyclability treatment.
