Synthesis of Copper Oxide Nanoparticles by Miscanthus Sinensis (Silver Grass) Leaf Extract

Abstract

In materials physics, “green” synthesis has gained attention as a sustainable, reliable and eco-friendly protocol for synthesizing a wide range of nanomaterials including metal/metal oxides nanomaterials, bioinspired, and hybridmaterials. In the past numerous years, the utilization of synthetic concoctions and physical strategies were in mould; however, the acknowledgment of their toxic impacts on human well-being and condition influenced serious worldview for the researcher. Since, green synthesis is the best option to option to opt for the synthesis of nanoparticle, therefore the nanoparticles were synthesized by using aqueous extract of Miscanthus Sinensis (Silver grass) and metal ions (such as Copper Oxide). Copper was of particular interest due to its distinctive physical and chemical properties. Miscanthus Sinensis leaf extract was selected as it is of high medicinal value and it does not require any sample preparation and hence is cost- effective. The fixed ratio of plant extract and copper ions were mixed and kept at room temperature for reduction. The colour change from Green to black confirmed the formation of nanoparticles. Further, the synthesized nanoparticles were characterized by standard Physio-chemical techniques like DLS, UV-VIS, AAS and zeta potential.
