The oxygen evolution reaction (OER), a cornerstone of electrochemical energy conversion systems such as water splitting and metal-air batteries, is inherently limited by its sluggish kinetics due to the multistep proton-coupled electron transfer (PCET) mechanism and high activation barriers . This anodic reaction involves the formation of molecular oxygen (O2) from water or hydroxide ions, proceeding through intermediates such as adsorbed hydroxyl (*OH), oxo (*O), and hydroperoxo (*OOH) species on the catalyst surface. The kinetics of OER are governed by the interplay of thermodynamics and surface kinetics, where the adsorption energy of intermediates, quantified by the Sabatier principle, dictates the activity of the catalyst .
