Developing heterostructure electrocatalysts is a possible route to discovering cost-effective and effectual catalysts for the oxygen evolution reaction. Er2O3–NiO nanoparticles have been created by successive drop cost method on nickel form. The produced Er2O3, NiO, and Er2O3–NiO electrocatalytic performances have been assessed, showing increased OER (185 mV@10 mA/cm2) activities compared to the single component. Furthermore, the three-electrode system (Er2O3–NiO) has remarkable OER properties, requiring only 1.37 V to reach 10 mA/cm2. Er2O3–NiO ‘s synergistic effect, which helps to cause lattice change into the fine structure of the crystal, activates the evolution of surface partial oxygen atoms and enables the lattice oxygen process, is principally responsible for its excellent catalytic performance and stability. This research contributes to a more profound knowledge of the synergistic interaction between various material oxides in heterostructure catalysts. It offers recommendations for future research and development of nanomaterials in sustainable energy conversion technologies.
