Abstract
Green Nanotechnology for nanoparticle synthesis using plants is gaining considerable interest among researchers as an eco-friendly alternative to conventional physical and chemical methods as this approach eliminates the use of toxic chemicals. The present study reports the synthesis of zinc oxide nanoparticles (ZnO-NPs) using Ocimum basilicum L. var. purpurascens Benth.-Lamiaceae leaf extract and zinc nitrate. Hexagonal (wurtzite) shaped ZnO-NPs with size about 50nm were synthesized and characterized using XRD, TEM and EDX analysis.
•Zinc oxide nanoparticles were produced by leaf extract mediated green synthesis.•The particles were about 50 nm in size with hexagonal crystalline morphology.•TEM and EDX analysis further confirmed the morphology, size, and elemental purity of the particles.
