Abstract

Copper Oxide/Carbon (CuO/C) nanocomposites were developed through the green method using the leaf extract of at room temperature. Here, the leaf extract serves as a capping agent, reducing agent and a source of carbon for the formation of nanocomposites. As we know, this is the first article on the synthesis of CuO/C nanocomposites using this leaf extract. The nanocomposites were prepared by mixing the copper sulphate pentahydrate solution with the plant extract under certain conditions. The synthesized material was characterized by XRD, UV-Visible, FTIR, FE SEM, EDS, XPS and TGA. The results revealed that the synthesized material is a composite of copper oxide and functionalized graphene-like carbon. The SEM images indicated that the CuO/C nanoflakes had an average thickness of 7-11nm. Further, the composites were examined for antifungal activity and antibacterial activity. The nanocomposites showed significant antibacterial activity against the pathogenic bacterial strains and and antifungal activity against the fungi and Also, the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal/Bactericidal Concentration (MFC/MBC) of the nanocomposites were determined against the fungus and the bacteria
