In the present work, the study based on the catalytic performance evaluation of chemically deposited Cu4SnS4 (CTS) thin film for oxygen evolution reaction activity (OER) is accomplished. The CTS thin films are deposited on nickel foam (NF) using successive ionic layer deposition and adsorption (SILAR) technique. The effects of varied SILAR deposition cycles on the OER activity of CTS films are evaluated using the electrochemical polarizing technique. The structural, microstructural and electrochemical properties of the films are studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and electrochemical impedance spectroscopy techniques (EIS), respectively. The optimized SILAR cycle deposited CTS film possess the lower overpotential of 350 mV with lower Tafel slope of 70 mV dec-1 and excellent stability retention of 84 % for 24 h. The presented results provide new platform for employing photovoltaic CTS compound as a catalyst in OER activity. |
