Abstract

An eco-friendly approach has been taken in the present study to synthesize copper nanoparticles from their salts (CuSO4) using Amaranthus spinosus. The leaf extract of Amaranthus spinosus involves the reduction of copper ions and also acts as a capping agent. Initially, the synthesis of copper nanoparticles was confirmed by visual observation, i.e., colour change (dark green colour), and it was characterized primarily by UV-vis spectroscopy and Fourier Transform Infrared spectroscopy. Further, the formation of the crystalline phase was analyzed by X-Ray Diffraction pattern. The size and morphology of the synthesized Copper nanoparticles was characterized by Field Emission Scanning Electron Microscopy and the elemental composition was analyzed by EDAX. The results of the present study confirmed that the leaf extract of Amaranthus spinosus is capable of producing nanoparticles. Keywords: Amaranthus spinosus, copper nanoparticles, green synthesis, eco-friendly synthesis.
