Abstract The rapid growth of the electric vehicle industry has driven up nickel demand for batteries. However, release various metals during smelting nickel‐containing ore leads to complex multi‐metal contaminated wastewater. Herein, CaFe layered double hydroxide (denoted as CaFe) is synthesized treatment wastewater, achieving removal efficiencies 98.0%, 98.6%, 100%, and 100% Co 2+ , Ni Cu Zn respectively. quasi‐situ X‐ray diffraction (XRD) absorption fine structure (XAFS) results indicate formation high‐entropy LDH CaCoNiCuZnFe by isomorphic substitution Ca in CaFe. Meanwhile, lattice distortion metal vacancies can be observed due introduction with different ionic radii dissolution . Given stability abundant active sites material, shows good OER performance an overpotential 310.7 mV at 10 mA cm −2 long‐term 250 h. Density functional theory (DFT) calculations reveal that optimizes intermediate adsorption energy enhancing M─O covalency vacancy activates oxygen generating non‐bonding oxygen, which synergistically triggers mechanism (LOM). This strategy converts wastewater resources into valuable products achieves dual goals environmental remediation resource utilization.
