Strategies for the enhancements in catalytic performance and stability of anodic electrocatalyst in PEM water splitting

This article presents a strategy for enhancing the catalytic performance and stability of anodic electrocatalysts in proton exchange membrane (PEM) water splitting. PEM water splitting is a sustainable method for producing hydrogen and oxygen from water utilizing electrocatalysts. However, the performance and stability of the anodic electrocatalysts employed in this process are crucial for its commercialization due to harsh condition causing low stability. The main focus in this review article is the strategies for improving the catalytic performance as well as stability of the anodic electrocatalysts, such as doping with heteroatoms, and alloying with other metals. The results demonstrate that these modifications can significantly enhance the catalytic performance and stability of anodic electrocatalysts in PEM water splitting. These strategies open new possibilities for the development of efficient and stable electrocatalysts for PEM water splitting, paving the way for its commercialization and widespread use in clean energy applications.
