摘　　要：Metal-cation doping is a fundamental strategy for enhancing catalyst performance.Fe-doped Ni_(0.85)Se/NF(Fe-Ni_(0.85)Se/NF)nanoparticles were prepared at 80°C via Fe^(2+)etching method.The addition of Fe altered the coordination environment of the Ni species along with the catalyst's morphology,creating additional active sites.Notably,the synergistic interaction between the bimetallic components augmented the built-in activity and accelerated reaction kinetics.The Fe-Ni_(0.85)Se/NF electrocatalysts demonstrated remarkable catalytic activity for the oxygen evolution reaction(OER),with an acceptable overpotential of 276 mV and a Tafel slope of 58.1 mV dec^(−1)at 100 mA cm^(−2).Moreover,they demonstrated exceptional durability.In situ Raman and X-ray photoelectron spectroscopy(XPS)analyses showed that the excellent OER performance stemmed from the reconstruction-induced hydroxyl oxide.This study offers a novel approach for streamlining the synthesis procedures and reducing the experimental costs for developing high-efficiency electrocatalysts.
