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