| Abstract | The design and development of cost-effective and highly efficient oxygen evolution reaction (OER) electrocatalysts are urgently desirable during the water-splitting process. Here, NixFe80-xB20 (x = 70, 60, 50, 40, 30, hereafter referred to as NFB) amorphous alloys, with high mechanical strength, excellent corrosion resistance, and unique atomic structure, are fabricated as efficient water oxidation electrocatalysts in alkaline solutions. Ni40Fe40B20 amorphous ribbons achieve only 319 mV of overpotential at 10 mA center dot cm-2 with a Tafel slope of 56 mV dec-1 and exhibit excellent long-term stability for 24 h at 10 mA center dot cm-2 and 100 mA center dot cm-2 in 1 M KOH solution, which outperform the commercial RuO2 electrocatalyst. It is worth noting that the OER performance of NixFe80-xB20 amorphous electrocatalysts after long-term chronopotentiometry test displays more effectively, which can be ascribed to the surface construction. Meanwhile, the analysis of the morphology and structure of the electrocatalysts reveal that continuous oxidation during the OER process induces the structural reorganization on the surface of the electrocatalysts, which can enhance the electron transfer process , adsorption of the reaction intermediates to optimize the OER performance. This study provides a shred of evidence for surface self-reconstruction of NiFeB amorphous alloys electrocatalysts during the OER process and promotes the appli-cation of amorphous alloys as functional materials in the water-splitting field.
