A highly active electrocatalyst Ni-Fe-P-WO3/NF was synthesized through a simple electroless deposition method on nickel foam, showing superior catalytic performance compared to noble metal catalyst IrO2/NF for the oxygen evolution reaction.
The proper construction of high efficiency, low-cost, earth-abundant oxygen evolution reaction (OER) catalyst is essential for hydrogen formation by water splitting. A novel electrocatalyst with highly active OER performance was manufactured by a simple elec-troless deposition method of Ni-Fe-P-WO3 on nickel foam (NF). Benefiting from outstanding mass transfer capability of Ni-Fe-P-WO3/NF heterogeneous structure, abundance of active sites in the amorphous architecture and etc., the Ni-Fe-P-WO3/NF shows extremely superb electrocatalytic properties compare to noble metal catalyst IrO2/NF for OER, which needs an overpotential of only 218 mV in 1.0 M KOH solution to achieve the current density of 10 mA cm-2. It also has remarkable OER activity at high current density that only needs 298 mV to attain 100 mA cm-2 current density. Moreover, the Ni-Fe-P-WO3/NF has low Tafel slope of 42 mV dec-1. This study offers a novel approach to the production of OER multiphase electrocatalysts from oxides and alloys.(c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
