Abstract NiFe layered double hydroxides (LDHs) are state‐of‐the‐art catalysts for the oxygen evolution reaction (OER) in alkaline media, yet they still face significant overpotentials. Here, quantitative boron (B) doping is introduced LDHs (ranging from 0% to 20.3%) effectively tailor Ni‐Fe‐B electronic interactions enhanced OER performance. The co‐hydrolysis synthesis approach synchronizes hydrolysis rates of Ni and Fe precursors with formation rate B─O─M (M: Ni, Fe) bonds, ensuring precise B into LDHs. It demonstrated that B, as an electron‐deficient element, acts “electron sink” at levels 13.5%, facilitating transition 2+ active 3+δ , thereby accelerating kinetics. However, excessive (13.5–20.3%) generates vacancies LDHs, which increases electron density sites hinders their reducing activity. Optimal performance achieved a level overpotential only 208 mV reach current 500 mA cm −2 placing it among most effective date. This engineering opens new avenues developing highly efficient anode water‐splitting hydrogen production.
