Abstract

The development of suitable support to maximize the atomic utilization efficiency of platinum is of great significance for the hydrogen evolution reaction (HER). Herein, we report a simple and fast nonequilibrium-corrosive approach to prepare oxygen defect-enriched Fe₃O₄ decorated with trace Pt onto nickel-iron foam (Pt/Fe₃O₄-O_v/NIF). The Pt/Fe₃O₄-O_v/NIF electrode is superhydrophilic with intimate contact with the electrolyte. In addition, the strong electronic interactions between Fe₃O₄ and Pt and the oxygen-rich vacancies contribute to the catalytic process and improve the electrochemical interfacial properties. Thus, the Pt/Fe₃O₄-O_v/NIF electrocatalyst only requires an overpotential of 29 and 39 mV at 10 mA cm^-2 in alkaline freshwater/alkaline seawater, respectively, exhibiting superior HER activity. Furthermore, the anion exchange membrane water electrolyzer (AEMWE) owns low cell voltage of 1.86 V at 1000 mA cm^-2 and long-term electrocatalysis durability. This work provides an effective approach for designing efficient AEMWE electrocatalysts for hydrogen production.
