Abstract The oxygen evolution reaction (OER) plays a pivotal role in diverse renewable energy storage and conversion technologies, including water electrolysis, electrochemical CO 2 reduction, nitrogen fixation, metal‐air batteries. Among various electrolysis techniques, proton exchange membrane (PEM)‐based devices offer numerous advantages, high current densities, exceptional chemical stability, excellent conductivity, high‐purity H . Nevertheless, the prohibitive cost associated with Ir/Ru‐based OER electrocatalysts poses significant barrier to broad‐scale application of PEM‐based splitting. Consequently, it is crucial advance development non‐noble metal catalysis substance acid‐activity thereby fostering their widespread integration into PEM electrolyzers (PEMWEs). In this review, comprehensive analysis acidic mechanism, encompassing adsorbate mechanism (AEM), lattice (LOM) oxide path (OPM) offered. Subsequently, systematic summary recently reported noble‐metal‐free catalysts transition metal‐based, carbon‐based other types provided. Additionally, compilation situ/operando characterization techniques provided, serving as invaluable tools for furnishing experimental evidence comprehend catalytic mechanism. Finally, present challenges future research directions concerning precious‐metal‐free are comprehensively summarized discussed review.
