The significant threat posed by the high toxicity of heavy metals and antibiotics in water pollutants has prompted a growing emphasis on development highly efficient removal methods for these pollutants. In this paper, flexible electrospinning polyacrylonitrile (PAN) nanofiber-supported CdBi2S4 was synthesized via hydrothermal method, followed amination treatment with diethylenetriamine (DETA). as-prepared CdBi2S4/NH2–PAN nanofiber, enriched sulfur vacancies, demonstrated outstanding visible-light trapping ability suitable band gap, leading to separation transport photogenerated carriers, ultimately resulting exceptional photocatalytic capability. optimal 3-CdBi2S4/NH2–PAN nanofiber achieved impressive reduction rates 92.26% Cr(VI) 96.45% tetracycline hydrochloride (TCH) within 120 min, which were much higher than those CdS/NH2–PAN, Bi2S3/NH2–PAN, CdBi2S4/PAN nanofibers. After five cycles, rate consistently remained above 90%. Their ease recovery from application environment contributes their practicality. Additionally, compared conventional suspended particle catalyzers, composite exhibited remarkable flexibility self-supporting properties.

Photocatalytic Degradation of Organic Pollutants by Sulfate Radicals Activated by Defective NH₂-MIL-88B

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Май 8, 2025

Photocatalysis has been recognized as a viable technology for pollutant degradation in wastewater, owing to its ability generate reactive radicals under photoirradiation. Among these, sulfate (SO4·-) have attracting significant attention due their strong oxidizing properties; yet the specific mechanism of action remained elusive thus far. In this study, defective NH2-MIL-88B (DNMB) is prepared via facile hydrothermal procedure presence potassium sodium tartrate and found facilitate production from anions visible light irradiation, partial reduction Fe3+ Fe2+ NMB skeleton by added that enriches Fe3+/Fe2+ redox couples, addition other species like superoxide hydroxy radicals. This effectively improves efficiency toward variety organic pollutants, including antibiotics such tetracycline (TC), sulfamethoxazole (SMX), levofloxacin (LEV), well common contaminants bisphenol A (BPA) rhodamine B (RhB), compared pristine NMB. Specifically, after 40 minutes rate increases 61.5% 92.1% TC, 76.1% 89.4% SMX, 60.5% 75.2% LEV, 61.7% 91.2% BPA, 78.4% 94.8% RhB. The primary active are identified be radicals, with minor contributions holes, hydroxyl demonstrated quenching experiments electron spin resonance measurements, further confirmed theoretical studies. Degradation pathways various pollutants then proposed based on results Fukui index calculations liquid chromatography-mass spectrometry analysis. These underscore crucial role structural engineering driving advancement green sustainable technologies environmental engineering.
