Abstract The applications of Fe‐based electrocatalysts in oxygen evolution reactions (OER) and hydrogen (HER) are hindered due to poor stability catalytic activity originating from rapid Fe leaching the intrinsic electronic structure FeOOH. Here, study presents a strategy precisely continuously tune morphology FeOOH covalent characteristics Fe–O bonds by controlling coverage extracellular polymeric substances (EPS) on surface. Operando spectroscopy theoretical calculations reveal that regulating covalency induces changes intermediate adsorption strength metal leaching, leading volcano‐shaped trend durability as function covalency. Notably, HER, negatively charged sites EPS exhibit superior *H compared bare In particular, 2 @FeOOH exhibits excellent performance for both OER (η 10 = 240 mV) HER 52 mV), with outstanding over 200 hours at 100 mA cm⁻ . current density also reaches merely 1.51 V two‐electrode configuration, significantly surpassing other bifunctional electrocatalysts. This approach will provide promising pathway enhance water electrolysis through precise modulation coverage.
