Abstract:

The proper design of low-cost, efficient and earth-rich electrocatalysts for the oxygen evolution reaction (OER) plays a crucial role in hydrogen production by water splitting. In this work, we fabricated a novel nanocomposite electrocatalyst Ni-Fe-P-WO3 on nickel foam (NF) with highly active OER performance by a simple electroless deposition method. Benefiting from the outstanding mass transfer capability of the Ni-Fe-P-WO3/NF heterogeneous structure, the abundance of active sites in the amorphous architecture and the high electrical conductivity due to the nickel foam support, the composite electrocatalyst Ni-Fe-P-WO3/NF shows extremely excellent electrocatalytic performance than IrO2/NF noble metal catalyst towards OER, which requires a low overpotential of 218 mV at 10 mA cm-2 current density in 1 M KOH solution. And it also has remarkable OER activity at high current density that only needs 298 mV at 100 mA cm-2 current density in 1 M KOH. In addition, the Ni-Fe-P-WO3/NF has small Tafel slope that only 42 mV dec-1 and superior stability and durability for at least 24 h, which are outperforming those most of the reported OER electrocatalysts. This study provides a new approach to the preparation of heterogeneous catalysts using alloys and oxides for OER.
