N2 - Hydrogen production is still a significant challenge despite the importance of using the abundant elements on earth to create inexpensive, stable and highly effective electrocatalysts for oxygen evolution reaction. Studies have explored the feasibility of oxygen evolution reactions as an alternative for storing electrical energy. Research on oxygen evolution reaction has made significant progress, particularly in producing safe, efficient and commercially viable catalysts for OER. Recently, Perovskite-type oxides have emerged as intriguing and practical alternatives to non-precious metal catalysts. They possess the ability to serve as highly efficient catalysts in water-splitting systems. We fabricated SrCeO3/rGO nanocomposite in this study using the hydrothermal method. The synthesized nanocomposite's structural, morphological and electrocatalytic features have been examined with, X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical tests, accordingly. SrCeO3/rGO exhibits improved electro-catalytic performance to OER in an alkaline condition with a lower overpotential (235.70 mV) and Tafel plot (35.8 mV dec−1) compared with pure SrCeO3 electro-catalyst. Furthermore, cyclic stability and chronoamperometry analysis evaluated the electrodes' stability over 60 h. These remarkable electrochemical characteristics of the SrCeO3/rGO distinguish it as a suitable contender for future OER applications.
