Abstract How to manipulate heterostructure engineering achieve high‐efficiency oxygen evolution reaction (OER) remains a significant challenge. Herein, promising OER electrocatalyst with IrNi nanoalloys (≈3.29 ± 0.12 nm) anchored on NiFe‐MOFs (IrNi@NiFe‐MOFs), exhibiting promoted phase transformation and self‐optimized dynamic interface electronic structure, via one‐step hydrothermal method is designed developed. Specifically, IrNi@NiFe‐MOFs displays excellent performance low overpotential of 228 mV at 10 mA cm −2 , small Tafel slope 37.6 dec −1 robust stability 100 . Experimental theoretical calculations identify the actual active sites as IrNi@NiFeOOH further reveal that structure electron by engineering, boost its catalytic performance. Moreover, strong interactions unique resulting in better charge redistribution adaptive bonding (Ir─O─Ni/Fe bonds). This therefore plays critical role promoting transfer, facilitating intermediates, reducing energy barrier potential‐determining step, thereby boosting These findings provide new insights into development MOF‐based electrocatalysts engineering.
