Abstract

Hydrogen produced from water has become a competitive substitute for fossil fuels. Numerous materials have been studied in this area as electrocatalysts for the production of clean hydrogen. In present work, we propose a hydrothermal method to synthesize the Ag-MoS₂ for both oxygen evolution process (OER) plus hydrogen evolution process (HER). Furthermore, electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV), and cyclic voltammetry (CV) tests were performed in an alkaline electrolyte to assess the electrochemical performance. The Ag-MoS₂ has an overpotential of 280 mV, 262 mV for OER and HER, correspondingly. Moreover, the Ag-MoS₂ exhibits a lower Tafel slope of 53.8, and 112 mV dec⁻¹ for OER and HER, compatibly. On the other hand, chronoamperometry tests validated the stability of synthesized Ag-MoS₂. Hence, the peculiar and outstanding properties of Ag-MoS₂ make it a promising candidate for next-generation electrochemical energy applications.
