Abstract
This investigation delved into the field of bifunctional electrocatalyst water splitting, aimed at advancing sustainable energy by addressing the scarcity of efficient nonprecious electrocatalysts capable of facilitating both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). This study focused on nanohybrids consisting of hydrothermally synthesized rGO/MnO2/MoS2 composites and highlighted their efficacy as bifunctional electrocatalysts. The synergistic integration of rGO/MnO2/MoS2 enhanced the surface area, magnified electroactive sites, established a customized conductive arrangement, and provoked the efficiency in splitting of water. The nanohybrid displayed exceptional catalytic performance for the OER and HER, with significantly reduced overpotentials of 208 and 205 mV in 1 M KOH at 10 mA cm-2 current density, respectively. The findings underscore the potential of these cost-effective and environmentally friendly rGO/MnO2/MoS2 nanohybrids in advancing the field of electrocatalysis for renewable energy applications.
