Synthesis and characterization of zinc oxide nanoparticles (ZnO-NPs) from leaves of some plants

The current study focuses on producing zinc oxide nanoparticles (ZnO-NPs) from aqueous leave extracts because it is more environmentally friendly and cost-effective than traditional physical and chemical methods. Synthesis of aqueous extracts of Moringa Oleifera, Ocimum tenuiflorum (Tulsi), and Neem (Azadirachta indicia) leaves . Zinc acetate dihydrate (Zn (CH 3 COO) 2 .2H 2 O) was used as a precursor to biosynthesize ZnO-NPs at different temperatures (50, 75, and 100 o C) for 1 hour of the synthesis of Zinc oxide nanoparticles (ZnO-NPs) were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared (UV). The presence of biomolecules such as polyphenols, carboxylic acid, polysaccharides, and amino acids was revealed by FTIR analysis of green synthesized nanoparticles. The results of the SEM study of green synthesized ZnO nanoparticles revealed that the sample exhibits a compact arrangement of homogeneous nanoparticles with a spherical shape and successfully unfolded it was crystalline structure nature.
