Abstract
Currently, sustainable energy production is the most needful and challenging factor due to the increase of major energy consumption such as fossil fuels, gas fuels, coal, and petroleum. Hydrolysis technology is one of the promising factors to generate clean energy production. Especially, electrochemical water splitting involves two half reactions, i.e., hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). OER is a four electron process and it possessed a slow kinetics and high overpotential. The aim of this study is to overcome the difficulties of energy consumption, and enhances its kinetic activity and also reduces its overpotential by doping agent. In this study, pristine and 5, 10% Ag-doped CdS nanostructures were synthesized via co-precipitation method. Interestingly, 10% Ag-doped CdS nanostructure exhibits 868.7 F/g specific capacitance at 10 mV/s scan rate. Its OER activity, ion diffusion process, and stability were investigated under the linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), and chronoamperometry (CA) studies. Ag plays a vital role to overcome the difficulties and it is noteworthy for water splitting applications.
