Nickel-iron-based layered double hydroxides (NiFe LDHs) have attracted tremendous research and industrial interests for oxygen evolution reaction (OER) electrocatalysis. However, methodologies on simultaneous regulation of performance-influencing factors remain scarce their real synergistic effects are not clear enough. Herein, a versatile polyoxometallic acids (POMs) etching approach is reported to ingeniously reconstruct NiFe LDH, including 3D morphological nanotailoring, Fe3+ α-Ni(OH)2 active species reconfiguration, creation multiple Ni, Fe, O vacancies, intercalation POM polyanionic clusters. The experimental theoretical data collaboratively unveil that control the key mechanisms dominantly contribute step-like OER performance enhancement. reinforced electrocatalyst further produced with low cost high up Ф180 mm in diameter, showing its feasibility advancement promising configuration LDH-PMo12(+) II Ni@NiFe LDH(-) alkaline anion-exchange-membrane electrode stack cells. Furthermore, mathematically evaluate evolution, novel empirical formula proposed quantitative identification structure-activity correlations, which offers an opportunity first fast reliability materials screening.
