Abstract

The growing global demand for sustainable energy has made electrocatalytic water splitting an essential method for efficient hydrogen production and storage. Perovskite oxides are becoming increasingly recognized as effective electrocatalysts for the hydrogen evolution reaction (HER) due to their tunable composition, diverse band structure, outstanding charge transport properties, and beneficial electronic characteristics. Nevertheless, their practical use is frequently limited by issues like inadequate intrinsic activity, stability problems, and cost-related concerns. This review thoroughly evaluates the latest advancements in perovskite oxide-based HER catalysts, emphasizing strategies to improve their electrocatalytic performance. Various techniques, including surface modification, elemental doping, and defect engineering, are investigated to optimize electronic structures, enhance active site density, and boost electrochemical durability. Furthermore, the review addresses improvements aimed at increasing the scalability and cost-effectiveness of perovskite oxide-based electrocatalysts for hydrogen production. Lastly, the article outlines existing challenges and future outlooks to inform the strategic advancement of next-generation perovskite materials for sustainable hydrogen energy endeavors.
