Green Synthesis of Zinc Oxide Nanoparticles using Extracts of Ocimum Tenuiflorum and its Characterization

K. Dilip Kumar, K. Narayana, K. Appa Rao


Various applications of nanoparticles stimulate the need for synthesizing them. But, the conventional methods are usually hazardous and energy consuming. This leads to the focus on “green synthesis” of nanoparticles which was an efficient and eco-friendly approach. Natural diminishment operators are being investigated worldwide to limit the impacts of toxic chemicals utilized as a part of nanoparticles creation. The present study states a green approach for the synthesis of zinc oxide nanoparticles through a complex formation with plant extracts of ocimum tenuiflorum (Black Tulasi). Leaf extract was used as the biological reduction agent for synthesizing zinc oxide nanoparticles from zinc sulphate. The resultant nanopowder was characterized using various analytical techniques, such as X-ray diffraction, SEM, XRF, particle size analyser, the size range of nanoparticles obtained upon synthesis at optimum conditions was 50–63 nm as reported by TEM. X-beam diffraction examines affirmed the crystalline idea of the nanoparticles demonstrating molecule measure inside the range gave by electron microscopy information.


Keywords: Green synthesis, Ocimum tenuiflorum, zinc sulphate, SEM, TEM, XRF
