摘要

A bimetallic sulfide electrode Ni3Sb2S3 was fabricated by using a single-source precursor approach to reveal its supercapacitive efficiency. A narrow bandgap of 1.8 eV and average crystallite size of 40 nm were obtained. The presence of metal sulfide bonds was indicated by Fourier transform infrared (FTIR) spectra. A nonuniform nanorod morphology was revealed in this bimetallic chalcogenide. The electrochemical charge storage behavior was tested in this study. According to cyclic voltammetry results, the generated electrode revealed excellent charge storage abilities, with a specific capacitance of 2773.074 F g−1. This implies that the electrode has strong potential for storing energy. Additionally, electrochemical impedance studies revealed a series resistance of Rs = 2.5 Ω. The electrocatalytic performance of the electrode revealed an oxygen evolution reaction (OER) overpotential of 306 mV coupled with a Tafel slope of 145 mV dec−1. Conversely, its hydrogen evolution reaction (HER) activity exhibited an overpotential of 132 mV with a corresponding Tafel slope of 43 mV dec−1 and supported favorable electrochemical activity.
