Abstract The demand for renewable energy sources has become more urgent due to climate change and environmental pollution. oxygen evolution reaction (OER) plays a crucial role in green sources. This article primarily explores the potential of using non‐noble metals, such as transition rare earth enhance efficiency OER process. Due their cost‐effectiveness unique electronic structure, these metals could be game‐changer field. ′Doping,′ which is process adding small amount impurity material alter its properties, ′synergistic effects,′ refer combined effect two or elements that greater than sum individual effects, are key concepts this Transition can reduce overpotential, measure excess required drive reaction, thus enhancing by engineering surface molecular structure. summarizes roles various highlights opportunities researchers propose innovative ways optimize
