This research focuses on the environmentally friendly synthesis of CuO-ZrO2 nanocomposites using bioactive compounds of A. viridis. The synthesized material shows promising properties for supercapacitor and water splitting applications, with high specific capacitance and efficient catalytic activity.
The present research focused on environmentally benign synthesis of CuO-ZrO2 nanocomposite using bioactive compounds of A. viridis. Phase analysis of CuO-ZrO2 using Xray diffraction revealed the crystal size of 30.3 nm. Scanning electron microscope showed spherical-shaped nanoparticles of 88 nm size. The band gap value of 2.25 eV was obtained. The synthesized CuO-ZrO2 material was further investigated as electrode material for supercapacitor and water splitting studies. Cyclic voltammetry was used to estimate the specific capacitance value of 374.7 F/g, and galvanostatic charge discharge was used to determine the specific capacitance value of 286.3 F/g. Electrochemical impedance spectroscopy (EIS) and linear sweep voltammetry (LSV) were used to conduct HER and OER experiments. Tafel value of 143 mV/dec and overpotential value of 225 mV was recorded for composite by LSV for hydrogen evolution reaction.
