Improved synthesis of copper oxide nanosheets and its application in development of supercapacitor and antimicrobial agents

Copper oxide (CuO) nanosheets (NSs) have been synthesized using improved chemical bath deposition (CBD) method and used as energy materials in supercapacitor devices. The quality of CuO-NSs were investigated using different techniques such as, cyclic voltammetry, galvanostatic charge/discharge measurements, and electrochemical impedance spectroscopy. The structure, composition, and morphology of CuO-NSs were examined by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), energy dispersion spectrum (EDS). CuO-NSs device exhibited maximum specific capacitance about 564 Fg(-1) at 5 mV/s. Antibacterial properties of CuO-NSs with Bacillus subtilis and Salmonella typhimurium have shown promising prospects for the development of antibacterial agents.
