Although amorphous catalysts improve hematite (<em>α</em>-Fe<sub>2</sub>O<sub>3</sub>) photoanode activity, their defect-enabled functionality inherently accelerates structural degradation, exacerbating chloride-induced corrosion. Here, a synergistic dual-functional nano-armor is designed by anchoring phosphate (PO<sub>4</sub><sup>3−</sup>) to active sites on amorphous NiMoO<sub>4</sub> (a-NiMoO<sub>4</sub>@PO<sub>4</sub><sup>3−</sup>), achieving dual activity-stability enhancement. Detailed physicochemical characterization and density functional theory (DFT) calculations show that the successful and stable anchoring of phosphate is highly dependent on the amorphous structural properties of a-NiMoO<sub>4</sub>.

Moreover, OH<sup>−</sup> ion conduction follows a mixed vehicular and Grotthuss mechanism, causing highly mutable ion identity and number, as well as superior dynamics due to proton transfer.
