Redefining the Stability of Water Oxidation Electrocatalysts: Insights from Materials Databases and Machine Learning

ACS Materials Letters, Journal Year: 2024, Volume and Issue: 6(7), P. 2905 - 2918

Published: June 10, 2024

Research on electrochemical water splitting has experienced significant growth in interest transition metal borides, carbides, pnictides, and chalcogenides, owing to their notable catalytic performance. These materials, collectively called X-ides, are often considered promising electrocatalysts for the oxygen evolution reaction (OER). However, under strongly oxidizing conditions of OER, X-ides act as precatalysts, undergoing situ reconstruction a different, catalytically active phase. Discrepancies exist literature, with some studies claiming absence such transformations. Building upon previous efforts elucidate performance trends community, this Perspective discusses more nuanced approach X-ide research, emphasizing need reassess our understanding chemical stability significance process. By discussing role experimental computational databases, we present strategies predicting stress importance thorough validation. Moreover, highlight use machine learning extract meaningful insights from these data urge community adopt standardized, systematic reporting Finally, provide strategic guidelines directions advance ultimately enhancing future application sustainable hydrogen economy.
