Abstract The green synthesis method which is aligned with the sustainable development goals (SDGs) theory, proposed to synthesize ZnO nanoparticles using ginger extract treat acidic wastewater and factory effluent as a current challenge effects of concentration extracts on synthesized nanostructures are investigated. results declare that single-phase hexagonal formed less than 25 mL crystallite size NPs increased increasing extract. Also, significant morphology (nanocone, nanoflakes, flower-like) particle demonstrated. low leads formation while flower-like structure gradually completed by Furthermore, changes in specific surface area (SSA) samples observed (in range 6.1–27.7 m 2 /g) variation best SSA related 10 strong effect reflectance spectra NPs, especially UV region proved. indirect (direct) band gap energies obtained 3.09–3.20 eV (3.32–3.38 eV). photocatalytic activities for degradation methylene blue indicate impressive efficiency it reaches up 44% 83% prepared 5 pH 4.3 5.6, respectively.

Zinc oxide nanoparticles (ZnO NPs) were formed through a simple green synthesis route using Vitex negundo (V. negundo) leaf extract as reducing and capping source. Morphological, structural, chemical optical features of prepared ZnO NPs examined by field emission SEM, XRD, EDAX, PL, FTIR UV-vis DRS, respectively. FESEM images precisely visualized morphology the spherical with particles size ranges between 5 35 nm having mean diameter ∼19 nm. XRD pattern revealed formation hexagonal wurtzite structured high crystallinity. Asymmetric stretching vibration Zn-O bond analysis confirmed NPs. Catalytic activity was assessed against methylene blue (MB) dye degradation under natural sunlight illumination. Results photocatalytic experiment disclosed an impressive MB efficiency 98.50% at 60 min. Moreover, synthesized exhibited maximum mineralization (TOC removal) 92.34% h

Zinc oxide nanoparticles (ZnO NPs) have been successfully prepared using Cocos nucifera leaf extract and their antimicrobial, antioxidant photocatalytic activity investigated. The structural, compositional morphological properties of the NPs were recorded studied systematically to confirm synthesis. aqueous suspension showed an ultraviolet-visible (UV-Vis) absorption maxima 370 nm, indicating primarily its formation. X-ray diffraction analysis identified with a hexagonal wurtzite structure average particle size 16.6 nm. Fourier transform infrared some biomolecules functional groups in as responsible for encapsulation stabilization ZnO NPs. Energy-dispersive desired elemental compositions material. A flower-shaped morphology was observed by scanning electron microscopy, grain around 15 optical UV-Vis spectroscopy, band gap calculated 3.37 eV. demonstrated antimicrobial against T. harzianum S. aureus, zone inhibition 14 10 mm, respectively. behaviour absorbance degradation at 640 nm it discoloured methylene blue dye after 1 h, maximum 84.29%. Thus, could potentially be used antibiotic development pharmaceutical industries, photocatalysts.

Artemisia absinthium (A. absinthium) leaf extract was successfully used to create zinc oxide nanoparticles (ZnO NPs), and their properties were investigated via several techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive (EDX), Fourier transform infrared (FTIR), ultraviolet–visible spectroscopy (UV–Vis spectroscopy). SEM analysis confirmed the spherical elliptical shapes of particles. Three different peaks observed EDX at energies 1, 8.7, 9.8 keV, together with a single oxygen peak 0.5 keV. The XRD identified ZnO NPs as having hexagonal wurtzite structure, particle size that decreased from 24.39 18.77 nm, an increasing surface area (BET) 4.003 6.032 m2/g for (without extract) green NPs, respectively. FTIR groups molecules accountable stabilization minimization which apparent 3400 cm. Using UV–Vis spectroscopy, band-gap (Egs) estimated, values 2.65 2.79 eV,

In the realm of nanoparticles, metal-based nanoparticles have traditionally been regarded as pioneering category. Compared to other zinc oxide several advantages, including optical and biological properties, which provide them a significant competitive advantage in clinical applications. current investigation, we used an aqueous Mangifera indica seed extract synthesize (ZnO NPs). UV-Vis spectroscopy, Fourier transform infrared spectroscopy analysis, atomic force X-ray diffraction, scanning electron microscopy, transmission microscopy were characterize synthesized ZnO NPs. The assessed for their potential inhibit bacterial growth protect cells from free radical damage. According study's findings, that had modified with aid mango seeds very efficient preventing development tested bacteria also powerful antioxidants.

In this study, zinc oxide nanoparticles (ZnO NPs) were synthesized using an aqueous extract of the Ocimum lamifolium (O. lamifolium) plant. The I-optimal coordinate exchange randomized response surface methodology (RSM) was used to optimize effect acetate precursor, temperature, and time on ZnO NPs by designing nine runs. From ANOVA analysis, significance validity designed model showed that optimal values during synthesis found be ∼0.06 M, ∼30 °C, ∼1.35 h, respectively. obtained under these optimized conditions characterized explored UV–vis, TGA/DTA, FTIR, XRD, SEM-EDX, TEM, HRTEM, SAED. Furthermore, electrocatalytic performance performed for sulfamethoxazole (SMZ) sensing activity with a 0.3528 μM (S/N = 3) limit detection (LOD). addition, antibacterial study revealed confirmed excellent zone inhibition against E. coli, S. aureus, P. aeruginosa, pyogen pathogenic drug resistance bacterial strains at concentrations 50, 75, 100 μg/mL. Thus, O. leaf have potential diverse organic pollutant as well desirable material such antimicrobial strains.
