Bimetallic oxides are promising electrocatalysts due to their rich composition, facile synthesis, and favorable stability under oxidizing conditions. This paper innovatively proposes a strategy aimed at constructing one‐dimensional heterostructure (Fe–NiO/NiMoO 4 nanoparticles/nanofibers).

Abstract The rising demand for sustainable green hydrogen production necessitates efficient and cost‐effective water‐splitting electrocatalysts. Inspired by the catalytic activities of columbite‐tantalite, this study combines a scalable cutting‐edge synthesis approach with atomic‐level structures metal‐center‐mediated mechanisms to unravel its operational performance stability. Using ad in situ X‐ray absorption fine structure combined Density Functional Theory (DFT), results reveal distinctive valence band peaks moderate charge transfer from Mn Fe sites, enabling stable adsorption reduced activation barriers. In contrast, high‐valence Nb Ta centers at B‐sites promote favorable d ‐band alignment, enhancing orbital overlap oxygen p‐ orbitals. This facilites electronic delocalization, lowers accumulation, reduces barriers intermediates species. A‐sites exhibit strong redox reactivity optimal OH* O*, supporting electron fransfers. Solvation effects modeled via VASPsol further stabilize key intermediates, especially reducing energy barrier water dissociation. Notably, FeMn(NbTa) 2 O 6 ‐columbite catalysts stand out cell voltage 1.81 V current density 700 mA cm −2 , compared 40% Pt/C‐RuO₂ (1.75 V) same anion exchange membrane electrolyzer (AEMWE). Also, exhibits long‐term stability 800 surpassing benchmark Pt Vulcan‐RuO after 200 h AEMWE. work significantly advances research establishes design rule selecting metal compositions development advanced electrocatalysts alkaline electrolyzers.
