Опубликована: Фев. 21, 2025

This work focuses on the green synthesis of zinc oxide nanoparticles (ZnO NPs) to be used as a photocatalyst, preparing blueberry (Vaccinium corymbosum) extract reducing agent, chloride precursor, and NaOH precipitating agent (1, 7 14 M). Characterization techniques included X-ray diffraction (XRD), transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis), Fourier-transform infrared (FTIR), photoelectron (XPS), Raman spectroscopy. The XRD analysis confirmed hexagonal wurtzite crystalline structure ZnO NPs, while SEM TEM revealed flower-like morphology. Moreover, NPs exhibited band gap energy in range 3.17 3.27 eV, depending concentration NaOH. Regarding photocatalytic activity, synthesized showed efficiency greater than 90%, degrading malachite (MG) dye 60 min under sunlight. proposed mechanism includes reactive oxygen species (ROS) generation (hydroxyl radicals (OH•) superoxide (O2−)). also that maintained structural integrity after repeated cycles, emphasizing their stability suitability for practical applications.

Abstract Due to its unique properties and advantageous traits, zinc oxide has garnered significant attention in recent years for the green synthesis of ZnO nanoparticles (ZnO‐NP). This paper is focused on ZnO‐NPs mediated by Adiantum capillus‐veneris L. leaf extract assesses their potential biological activities. In this study, ZnO‐NP synthesized using A. L . extract. The are characterized using, UV–vis spectroscopy, energy‐dispersive X‐ray spectroscopy (EDX), (SEM) scanning electron microscopy, diffraction (XRD), Fourier transform infrared (FT‐IR) spectrophotometry. antibacterial, antifungal, anti‐inflammatory, antioxidant formulated also inspected. UV–vis, XRD, SEM, EDX, FTIR confirmed formation purity ZnO‐NPs. exhibit efficient antimicrobial potency against Escherichia coli , Pseudomonas aeruginosa Staphylococcus aureus Aspergillus niger fumigatus Gram‐positive bacteria, particularly S. more susceptible ZnO‐NPs, with largest inhibition zone 32 mm. contrast, E. P. display smaller zones 25 27 mm respectively. Anti‐inflammatory tests show that have a anti‐inflammatory effect egg albumin bovine serum denaturation, possess low toxicity erythrocytes, highly hemocompatible.

Desalination and Water Treatment, Год журнала: 2024, Номер 319, С. 100566 - 100566

Опубликована: Июнь 26, 2024

This study investigates the use of ZnO NPs (Zinc oxide nanoparticles) derived from spinach leaf extracts in a sustainable photocatalytic technology to enhance decomposition hazardous effluents refineries and paper mills. The biosynthesized were characterized through X-ray diffraction (XRD), UV-Vis spectroscopy, scanning electron microscopy (SEM), transmission (TEM). XRD analysis reveals that possess hexagonal wurtzite structure, exhibiting preferred arrangement (101) planes. synthesized have spherical shape, as seen SEM images. TEM detected size be between 35 40 nm. results indicate produced via biosynthesis activity efficiently decomposing organic chemicals found gasoline refining effluent when exposed light. At pH 8, exhibited highest rate degradation for toluene (84.26 %) xylene (90.36 after being simulated sunlight 240 min. In context treatment mill effluents, it has been shown subsequent cycles resulted reduction chemical oxygen demand (COD) levels 81.24 %, 74.14 68.92 60.24 53.82 respectively.
