Oxygen evolution reaction (OER) is crucial for the development of renewable energy conversion and fuel cell technologies. For the commercial application of these technologies, it is important to develop high-performance, inexpensive, and durable OER electrode materials. Recently, transition metal (TM)-based electrocatalysts, such as TM oxides, chalcogenides, carbides, nitrides, phosphides, and borides, have gained attention due to their cost-effectiveness, enhanced electronic conductivity, and multiple valence electron configurations. In this review, we discuss the latest advancements in TM-based OER electrocatalysts in alkaline media over the last five years. Additionally, the OER activity parameters and the active sites are investigated for future augmentation in designing OER electrocatalysts for energy conversion devices. Finally, the prospects for developing efficient TM-based OER electrocatalysts are discussed.
