A facile partial phosphating strategy is reported to prepare an Fe-doped NiTe–Ni 12 P 5 catalyst on a nickel foam substrate using an Fe-doped NiTe nanosheet array precursor. Fe-NiTe–Ni 12 P 5 shows remarkable OER activity and stability in an alkaline electrolyte due to the synergistic effects among Fe-doping, NiTe, Ni 12 P 5 and the newly formed γ-NiOOH, which enable high explosion of active sites, well-modulated electronic structures, and promoted mass/charge transfer.
