Abstract :

The evolution of green chemistry for the synthesis of nanoparticles using plants, enzymes, microorganisms is gaining a considerable interest among the researchers as an ecofriendly alternative to chemical and physical methods. The biogenic Zinc Oxide nanoparticles were synthesized using the Ocimum tenuiflorum. Structural, morphological, particle size and optical properties of the synthesized nanoparticles have been characterized by using UV-Vis spectrophotometer, Fourier Transform Infrared (FTIR) spectroscopy, Field Emission Scanning Electron Microscope (FE-SEM), Energy Dispersive X-ray Spectroscopy (EDS or EDX), Zeta Potential, X-ray diffraction (XRD). The UV-Vis spectrum showed an absorption peak at 380 nm that reflects Surface Plasmon Resonance (SPR). The optical measurements were attributed to the band gap 3.19ev at pH12. The Zeta potential value of -36.4 ev revealed the surface change of green synthesized ZnO nanoparticles. The antioxidant activity was carried out by Diphenylpicrylhydrazyl (DPPH) and Reducing power assay. Green synthesized ZnO nanoparticles showed maximum inhibition (65.23%) and absorbance (0.6 a.u). This approach offers environmentally beneficial alternatives by eliminating hazardous chemicals and promotes pollution prevention by the production of nanoparticles in their natural environs.
