Green synthesis using plant extracts such as Ocimum basilicum L. (OBL) seed has attracted attention due to its sustainable and environmentally friendly nature. In this study, ZnO-MgO-Mn2O3 nanocomposites were synthesized OBL extract at two different calcination temperatures of 500 °C 600 °C, evaluated in terms photocatalytic application cytotoxicity. Phytochemicals seeds act reducing masking agents the production route, which leads formation nanomaterials with unique properties. Characterization techniques, including XRD, FE-SEM, DRS used analyze structural, morphological, optical features nanocomposite. XRD results confirmed increasing crystal size from ~ 32 nm (500 °C) 84 (600 °C). Also, FE-SEM images showed irregularly shaped EDX spectra samples presence zinc, magnesium, manganese, oxygen elements. The behavior nanocomposite cacined was investigated for organic pollutants. Removal percentages 97% Eriochrome Black T dye (pH = 10 90 min), 99% methylene blue 60 89% methyl orange 105 86.9% Rhodamine B 3 min) obtained. Moreover, cytotoxicity on 4T1 cell line investgate effect biological systems, IC50 value obtained around 323 µg/mL.

The recovery of valuable resources from wastewater treatment plants (WWTPs) has received a great deal attention as part the concept circular economy. Anaerobic digestion for stabilizing sewage sludge in WWTPs, which produces biogas and stabilized biosolids, is mature technology used worldwide. However, despite necessity achieving safe reliable organic recycling, studies on effect some emerging micropollutants this process are rare. This knowledge gap growing relevance because increasing use endocrine-disrupting compounds (EDCs), microplastics (MPs), engineered nanoparticles (NPs) industry human life. These ubiquitous streams and, therefore, may have serious effects course anaerobic sludge, raising concerns about their environment. article provides comprehensive overview mechanisms by selected EDCs, MPs, NPs affect valorization with focus production CH4, H2, volatile fatty acids. study takes into consideration performance during all stages digestion, shifts microbial abundance diversity, activity key enzymes process.

This study aimed to synthesize a multicationic hydrotalcite and transform it into mixed oxide nanostructures (ZnO/TiO2/CeO2/Al2O3, referred as MixO) serve heterogeneous photocatalyst for degrading various pollutants, including methylene blue (MB), methyl orange (MO), paracetamol (PA), paraquat (PQ). The was synthesized via an ultrasound-assisted method calcined at 700 °C obtain the corresponding metal oxide. A comprehensive characterization of both (MC-LDH) oxides (MixO) performed using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), photoelectron (XPS), N2 adsorption–desorption, Fourier infrared (FTIR), Raman spectroscopy, pHPZC analysis. MixO sample exhibited optical bandgap 3.19 eV. Photocatalytic performance evaluated during 240 min UV irradiation, demonstrating high degradation efficiencies attributable synergistic interactions among ZnO, TiO2, CeO2. Degradation reached 99.3% MO 95.2% MB, while PA PQ showed moderate rates 60% 15%, respectively. kinetics all pollutant compounds followed Langmuir–Hinshelwood model. Additionally, catalyst maintained consistent over four consecutive cycles, highlighting its reusability stability. These findings underscore potential practical recyclable photocatalysts environmental remediation, particularly in wastewater treatment applications.
