Sulfite [S(IV)]-based advanced oxidation processes (AOPs) have emerged as a promising strategy to address ever-growing water pollution. In this study, novel three-dimensional hierarchical porous copper (3D-Cu) catalyst was fabricated via laser 3D printing. The 3D-Cu demonstrated remarkable efficiency an S(IV) activator for the efficient removal of tetracycline hydrochloride (TC), comparable that powder under similar conditions. Impressively, manifested superb stability and reusability, maintaining high reactivity even after 40 successive cycles. results indicated Cu(II) sites functioned active oxidative activation, with unique hierarchically structures enhancing accessibility these facilitating migration contaminants. Furthermore, ryegrass seeds Vibrio fischeri exposure experiments suggested mineralization process TC could effectively reduce its biotoxicity. Additionally, CaSO3/3D-Cu system exhibited excellent adaptability different natural matrices effective in eliminating contaminants actual wastewater. Overall, study provides new preparation durable heterogeneous activators advances application S(IV)-AOPs real-world wastewater treatment.

Photocatalysis Inhibits the Emergence of Multidrug-Resistant Bacteria in an Antibiotic-Resistant Bacterial Community in Aquatic Environments

Environmental Science & Technology, Год журнала: 2024, Номер unknown

Bacterial antibiotic resistance has recently attracted increasing amounts of attention. Here, an artificially antibiotic-resistant bacterial community (ARBC) combined with five different constructed bacteria (ARB) single resistance, namely, kanamycin (KAN), tetracycline (TET), cefotaxime (CTX), polymyxin B (PB), or gentamicin (GEM), was studied for the stress response to photocatalysis. With photocatalytic inactivation, transfer and diffusion genes (ARGs) in ARBC decreased, fewer multidrug-resistant (MDRB) emerged aquatic environments. After several days inactivation Luria broth cultivation, >90% ARB were transformed antibiotic-susceptible by discarding ARGs. Bacteria double dominant species (99%) residual ARB. The changes ARG abundance varied, decreasing GEM TET KAN genes. change level consistent abundance. Correspondingly, point mutations occurred KAN, CTX PB after which might be reason why these persisted longer ARBC. In summary, could reduce some ARGs inhibit emergence MDRB as well block This work highlights advantages long-term controlling facilitates a better understanding communities real

Efficient Removal of Antibiotic Resistance Genes through 4f‐2p‐3d Gradient Orbital Coupling Mediated Fenton‐Like Redox Processes

Angewandte Chemie, Год журнала: 2023, Номер 135(47)

Опубликована: Окт. 5, 2023

Abstract Peroxymonosulfate (PMS) mediated radical and nonradical active substances can synergistically achieve the efficient elimination of antibiotic resistance genes (ARGs). However, enhancing interface electron cycling optimizing coupling oxygen‐containing intermediates to improve PMS activation kinetics remains a major challenge. Here, Co doped CeVO 4 catalyst (Co−CVO) with asymmetric sites was constructed based on Ce 4f−O 2p−Co 3d gradient orbital coupling. The achieved approximately 2.51×10 5 copies/mL extracellular ARGs (eARGs) removal within 15 minutes, exhibited ultrahigh degradation rate (k=1.24 min −1 ). effective 4f‐2p‐3d precisely regulates distribution Ce−O−Co center microenvironment, while electronic structure states (especially occupancy e g ), promoting adsorption intermediates. generated by interfacial enhanced reduction reaction at site oxidation significant mineralization (83.4 %). continuous flow reactor for 10 hours significantly reduces ecological risk in actual wastewater treatment.
