Abstract
. Yet, achieving long-term activity and structural stability at high current densities (HCDs) remains a critical challenge. This review highlights strategies to advance NiFe-based OER catalysts for sustained high-current operation, focusing on recent innovations including heteroatom doping, vacancy engineering, heterostructure formation, active-site modulation, and self-healing mechanisms. Developments across oxides, (oxy)hydroxides, non-metallic heteroatomic composites, layered double hydroxides, metal-organic framework-derived materials, and noble-metal-integrated hybrids are examined to provide a rational design framework for robust and efficient OER catalysts. Key pathways to tune morphology, composition,…
