Abstract

A new type of highly active and cost-effective nanocomposite electrocatalyst Ni–Fe–P–FeMnO3 on nickel foam (NF) supports is designed and prepared by electroless composite deposition and rapid dealloying. The nanocomposite electrocatalyst Ni–Fe–P–FeMnO3/NF presents a more remarkable electrocatalytic performance than Pt/C noble metal catalysts towards hydrogen evolution reaction (HER), which demands a quite low overpotential of 16.62 mV at −10 mA cm−2 current density in 1 M KOH. The prepared Ni–Fe–P–FeMnO3/NF electrocatalyst exhibits remarkable oxygen evolution reaction (OER) activity as well, which requires only 297 mV and 219 mV of overpotential at 50 mA cm−2 and 10 mA cm−2 current density, respectively. Moreover, the overall water splitting activity of Ni–Fe–P–FeMnO3/NF as both anode and cathode achieves a low potential of 1.63 V (vs. RHE) at a current density of 10 mA cm−2.
