The development of acid-stable water oxidation electrocatalysts is crucial for high-performance energy conversion devices. Different from traditional nanostructuring, here we employ an innovative microwave-mediated electron–phonon coupling technique to assemble specific Ru atomic patterns (instead random Ru-particle depositions) on Mn0.99Cr0.01O2 surfaces (RuMW-Mn1-xCrxO2) in RuCl3 solution because hydrated Ru-ion complexes can be uniformly activated replace some Mn sites at nearby Cr-dopants through microwave-triggered coherent superposition with molecular rotations and collisions. This selective rearrangement RuMW-Mn1-xCrxO2 particular spin-differentiated polarizations induce localized spin domain inversion reversed parallel direction, which makes demonstrate a high current density 1.0 A cm−2 1.88 V over 300 h stability proton exchange membrane electrolyzer. cost per gallon gasoline equivalent the hydrogen produced only 43% 2026 target set by U.S. Department Energy, underscoring economic significance this nanotechnology.

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.
