Recently, cobalt-based oxides have received considerable attention as an alternative to expensive and scarce iridium for catalyzing the oxygen evolution reaction (OER) under acidic conditions. Although reported materials demonstrate promising durability, they are not entirely intact, calling fundamental research efforts understand processes governing degradation of such catalysts. To this end, work studies dissolution mechanism a model Co3O4 porous catalyst different electrochemical conditions using online inductively coupled plasma mass spectrometry (online ICP-MS), identical location scanning transmission electron microscopy (IL-STEM), differential (DEMS). Despite high thermodynamics tendency reflected in Pourbaix diagram, it is shown that cobalt kinetics sluggish can be lowered further by modifying protocol. For latter, identified study, several (electro)chemical pathways lead must considered. Hence, uncovers transient character provides valuable insights help stability already published works facilitate knowledge-driven design novel, stable, abundant catalysts toward OER environment.

Abstract Ongoing research to develop advanced electrocatalysts for the oxygen evolution reaction (OER) is needed address demand efficient energy conversion and carbon‐free sources. In OER process, acidic electrolytes have higher proton concentration faster response than alkaline ones, but their harsh strongly environment requires catalysts with greater corrosion oxidation resistance. At present, iridium oxide (IrO 2 ) its strong stability excellent catalytic performance catalyst of choice anode side commercial PEM electrolysis cells. However, scarcity high cost (Ir) unsatisfactory activity IrO hinder industrial scale application sustainable development technology. This highlights importance further on Ir‐based catalysts. this review, recent advances in are summarized, including fundamental understanding mechanism, insights into catalysts, highly electrocatalysts, common strategies optimizing The future challenges prospects developing effective also discussed.
