Abstract

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 of random Ru-particle depositions) on Mn_0.99Cr_0.01O₂ surfaces (Ru_MW-Mn_1-xCr_xO₂) in RuCl₃ solution because hydrated Ru-ion complexes can be uniformly activated to replace some Mn sites at nearby Cr-dopants through microwave-triggered energy coherent superposition with molecular rotations and collisions. This selective rearrangement in Ru_MW-Mn_1-xCr_xO₂ with particular spin-differentiated polarizations can induce localized spin domain inversion from reversed to parallel direction, which makes Ru_MW-Mn_1-xCr_xO₂ demonstrate a high current density of 1.0 A cm⁻² at 1.88 V and over 300 h of stability in a proton exchange membrane water electrolyzer. The cost per gallon of gasoline equivalent of the hydrogen produced is only 43% of the 2026 target set by the U.S. Department of Energy, underscoring the economic significance of this nanotechnology.
