摘要

In this work, the novel FeNi-LDH/NF and (Fe-Ni)Ox/NF were prepared using facile hydrothermal and calcination methods. The electrocatalyst FeNi-LDH/NF ((Fe-Ni)Ox/NF) exhibits excellent HER catalytic activity, and produced an overpotential of 147 (210) mV at 10 mA cm−2 with a small Tafel value of 97 (100) mV dec−1 in 1.0 M KOH electrolyte. Due to the high-density active centers exposed on the surface of FeNi-based hydroxides, their electrical conductivity, and the synergistic effect between the metals, the catalytic activity of FeNi-based hydroxides is superior to that of FeNi-based oxides. The overall experimental findings showcase a feasible approach for exploring the potential of the nonprecious metal-based FeNi-LDH/NF ((Fe-Ni)Ox/NF) nanoelectrocatalyst towards alkaline HER.
