Abstract
AbstractDeveloping excellent electrocatalysts to replace noble metal catalysts and improve hydrogen production via water splitting is a daunting task. Bimetallic transition metal phosphides (TMPs) display improved performance than monometallic transition metal phosphides due to their synergistic effects. Moreover, research has proven that supporting them on conductive substrates can further enhance their electrochemical performance. Recently, metal‐organic frameworks (MOFs) are incorporated into bimetallic TMPs for enhanced performance. This review starts with a synopsis of the reaction mechanisms and performance parameters of hydrogen evolution reaction (HER) electrocatalysts. Moreover, the strategies for enhancing the performance of bimetallic TMPs and improving the hydrophilicity of TMPs are also discussed. In conclusion, the challenges and perspectives of bimetallic transition metal phosphides are discussed. This review analyses the extensive progress in this research domain and proffers insights that can aptly guide the future development of more excellent TMPs and other transition metal electrocatalysts for enhanced hydrogen evolution reaction.
