Abstract

There is a great challenge to employ an electrocatalyst that has high efficiency, is earth-abundant, and is a non-noble metal for oxygen evolution reaction (OER). Herein, we reported a low-cost and highly efficient OER catalyst, Fe-doped NiCoP nanosheet arrays in situ grown on nickel foam (NiCoFeP/NF), which was synthesized via a simple and mild hydrothermal and phosphorization method. In 1 M KOH solution, the as-prepared NiCoFeP/NF produces a larger current density of 200 mA·cm –2 at a low overpotential of 271 mV and exhibits a low Tafel slope of 45 mV·dec –1, which is superior to commercial RuO 2 . The outstanding OER performance of the as-prepared NiCoFeP/NF can be attributed to the synergetic effects among Fe, Ni, and Co elements, unique nanosheet arrays structure, and the great intrinsic electrocatalytic activity. On the basis of the above factors, the as-prepared NiCoFeP/NF may work as a promising OER electrocatalyst.
