Abstract Introducing oxygen redox chemistry into cobalt oxyhydroxide effectively enhances catalytic activity by enabling direct O-O coupling, thereby bypassing the rate-limiting *OOH step in the conventional adsorbate evolution mechanism. However, the key challenge is to preserve the accessibility of non-bonding oxygen states while maintaining cobalt-oxygen covalency.

Abstract The oxygen evolution reaction underpins many energy conversion technologies, yet its performance is fundamentally constrained by sluggish reaction kinetics at catalyst surfaces. Current catalyst design remains largely empirical because most strategies correlate bulk structural descriptors with overall activity rather than resolving the intrinsic kinetics of elementary reaction steps.
