The sustainability of crop production is impacted by climate change and land degradation, the advanced application nanotechnology paramount importance to overcome this challenge. development nanomaterials based on essential nutrients like zinc could serve as a basis for nanofertilizers nanocomposite synthesis broader agricultural applications quality human nutrition. Therefore, study aimed synthesize oxide nanoparticles (ZnO NPs) using pecan (Carya illinoinensis) leaf extract investigate their effect growth, physiology, nutrient content, antioxidant properties mustard (Brassica juncea).The ZnO NPs were characterized UV-Vis spectrophotometry, Dynamic Light Scattering (DLS), X-ray diffractometer (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infra-Red Spectroscopy (FTIR). Mustard plants subjected different concentrations ZnONPs (0, 20, 40, 60, 80, 100 200 mg L-1) during vegetative growth stage.The spectra revealed absorption maxima at 362 nm FTIR identified numerous functional groups that are responsible capping stabilizing NPs. DLS analysis presented monodispersed 84.5 size highly negative zeta potential (-22.4 mV). Overall, enhanced chlorophyll content (by 53 %), relative water 46 shoot biomass, membrane stability 54 %) net photosynthesis significantly in dose-dependent manner. In addition, supplement augmented K, Fe, Zn flavonoid contents well reactive oxygen species increasing capacity leaves up 97 %.In conclusion, can be potentially used plant stimulant novel soil amendment enhancing yields. Besides, biofortification B. juncea with helps improve nutritional perhaps potentiates its pharmaceutical effects.

Enhanced photocatalytic activity of green synthesized zinc oxide nanoparticles using low-cost plant extracts

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: July 19, 2024

Abstract Developing stable and highly efficient metal oxide photocatalysts remains a significant challenge in managing organic pollutants. In this study, zinc nanoparticles (ZnO NPs) were successfully synthesized using various plant extracts, pomegranate (P.M), beetroot roots (B.S), seder, along with chemical process. The produced ZnO NPs characterized X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), ultraviolet–visible (UV–Vis), Field Emission Scanning Electron Microscope (FESEM), High-Resolution Transmission Microscopy (HRTEM), Surface Area. For all prepared samples, the results indicated that composition of extract affects several characteristics particles, such as their photocatalytic properties, energy bandgap (E g ), particle size, ratio two intensity (0 0 2) (1 0) crystalline planes. size varies between 20 30 nm. To examine NPs' activity presence UV light, Methyl Orange (MO) was utilized. E by method 3.16 e. V, whereas it 2.84, 2.63, 2.59 for P.M, Seder, B.S respectively. most effective NPs, Beetroots, exhibited degradation efficiency 87 ± 0.5% kinetic rate constant 0.007 min −1 . planes also examined to determine specific orientation is linked production oxygen vacancies ZnO, which enhances efficiency. Furthermore, increase effectiveness can be attributed improved light absorption inter-band gap states charge transfer.
