In operando XAS investigation on FeCoNi-based thin film unravels that Fe<sup>3+</sup>-assisted water dissociation promotes the formation of Co<sup>2+</sup>–μ-H–Ni<sup>3+</sup> species, and the conductive character of Co<sup>2+</sup>Ni<sup>3+</sup>-oxide matrix facilitates the coupling of adjacent [Fe<sup>4+</sup>O/Fe<sup>3+</sup>–O˙] motifs.
