Abstract Water splitting is a critical process for the production of green hydrogen, contributing to advancement circular economy. However, application water devices on large scale primarily impeded by sluggish oxygen evolution reaction (OER) at anode. Thus, developing and designing efficient OER catalysts significant target. NiFe‐based are extensively researched as excellent electrocatalysts due their affordability, abundant reserves, intrinsic activities. they still suffer from long‐term stability challenges. To date, few systematic strategies improving durability have been reported. In this review, various advanced introduced. Moreover, challenges in alkaline media, including iron segregation, structural degradation, peeling substrate summarized. More importantly, enhance highlighted opportunities discussed facilitate future studies electrolysis. This review presents design strategy anion exchange membrane (AEM) electrolyzers overcome OER, which also emphasizes importance media its significance achieving large‐scale commercialization.
