Summary: Efficient and cost-effective electrocatalysts are crucial for the rapid development of water-splitting technology for hydrogen generation. Transition metal phosphides (TMPs) have emerged as effective electrocatalysts for the oxygen evolution reaction (OER) due to their unique electronic structure and high catalytic activity. TMP-based heterostructure catalysts show superior OER activity compared to individual TMP catalysts as they increase the number of active sites in the catalysts and facilitate the adsorption of intermediates. This review discusses the catalytic mechanism, preparation methods, strategies for improving OER performance, and current challenges of TMP-based heterostructure catalysts for the OER.
