Synthesis of Copper Oxide Nanoparticles using Green Leaves Extract of Azadirachta Indica

Abstract

In this article, we present the green synthesis of copper oxide nanoparticles using leaf extract of Azadirachta Indica, characterization and their optical properties. Copper oxide nanoparticles were prepared at room temperature with the help of green principles using Azadirachta Indica leaf extract as this reduces the use and generation of hazardous substances. The leaf extract of Azadirachta Indica acts as a very good reducing agent and the synthesis of copper oxide nanoparticles are safer for the environment. The product was characterized by Scanning electron microscopy (SEM) with Energy Dispersive X-ray analysis (EDX) and UV-Visible spectroscopy. Morphology study indicates spherical nature of the nanoparticles and formation of copper oxide nanoparticles was confirmed by EDX. SEM analysis showed that the synthesized NPs were in the range of 50–200 nm. Furthermore, the estimated band gap was 2.4 eV as determined by UV-Visible spectral analysis. The outcomes of the synthesis certainly contribute to the developing a better understanding of simple, low-cost, green and nontoxic synthesis methods and growing the knowledge base needed to design a suitable risk assessment framework and for further useful applications.
