Abstract The contamination of ecosystems by pharmaceuticals and personal care products represents a significant threat to public health, necessitating innovative approaches clean wastewater before release into aquatic environments. Here, we review the emerging strategies methods for remediation gemfibrozil carbamazepine, emphasizing toxicological impacts, advanced oxidation processes, membrane-based removal techniques, underlying mechanisms driving these processes. We found that engineered composites with strong electron transfer capabilities can enhance efficiency as they boost generation highly oxidative radicals. For instance, nano zero-valent ion incorporated carbon–nitrogen composite removes 100% within 60 min. Similarly, ruthenium perovskite-based heterogeneous catalyst achieved elimination carbamazepine in 7.5

Developing a hybrid process for wastewater purification is of utmost importance to make conventional methods more efficient and faster. Herein, an effective visible light-active nickel-nickel oxide/carbon/graphitic carbon nitride (Ni-NiO/C/g-C3N4)-based nanocatalyst was developed. A based on ozonation Ni-NiO/C/g-C3N4 light photocatalysis applied decolourize the Congo red (CR), Alizarin Red S (ARS), real dairy industry wastewater. The synthesized catalyst characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Χ-ray powder diffraction (XRD), photoelectron (XPS), UV-Vis diffuse reflectance spectrophotometry (UV-Vis DRS). factors affecting catalytic were evaluated, including contact time, solution pH, initial dye concentration, etc. degradation rate CR ARS compared between photocatalysis, ozonation, integrated photocatalytic (PC/O3) methods. results showed 100% within 5 min 40 min, respectively, by PC/O3. reusability modified four successive regenerations achieved. composite could be considered effective, fast, reusable in PC/O3 complete decolourization

Preparation of ZnIn₂S₄/MoS₂–SA Photocatalyst Gel for Wastewater Treatment: Photocatalytic Performance and Solar Interfacial Evaporation

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Апрель 2, 2025

With the rapid advancement of industrialization, wastewater pollution has become an increasingly severe environmental issue. The integration photocatalysis with solar interfacial evaporation technology, which leverages abundant and clean energy power, drawn growing attention as effective solutions to this problem. In study, MoS2 nanosheets low-dimensional controllable morphology were successfully grown on layered ZnIn2S4 using a simple template method, resulting in novel nanoflower heterojunction photocatalyst. This photocatalyst was then combined sodium alginate, aerogels fabricated through directional freezing technology. ZnIn2S4/MoS2 photocatalytic aerogel demonstrated excellent performance under visible light, efficiently degrading various pollutants such rhodamine B(RhB)(30 min, 99%), methyl orange(MO)(30 tetracycline(TC)(1h, 88%), other antibiotics dyes. Notably, degradation efficiency for tetracycline remained at 88% even after five cycles use, highlighting aerogel's strong reusability stability across different pollutants. Additionally, current composite exhibits rate up 1.984 kg m-2 h-1 photothermal conversion 95.5%. These results demonstrate that is promising candidate sustainable water treatment, broad applicability stable polluted environments.
