  • 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). (C) 2020 Elsevier Ltd.
