Abstract NiFe‐based layered double hydroxides (LDHs) are among the most efficient oxygen evolution reaction (OER) catalysts in alkaline medium, but their long‐term OER stabilities questionable. In this work, it is demonstrated that structure makes bulk NiFe LDH intrinsically not stable and deactivation mechanism of further revealed. Both operando electrochemical structural characterizations show interlayer basal plane contributes to activity, slow diffusion proton acceptors (e.g., OH − )...
