Abstract

Abstract : Fe NPs-Ni3 S2 NA/NF-10 exhibited an overpotential of 206 mV at 150 mA cm −2, outmatching most non-noble OER catalysts reported so far. Abstract : Although recent studies on the oxygen evolution reaction (OER) have achieved great progress, it remains a great challenge to achieve a smaller overpotential at high current density. In order to further improve the performance of the OER, we adopted a novel method to load Fe nanoparticles on a Ni3 S2 nanoplate array grown on nickel foam (Fe NPs-Ni3 S2 NA/NF) which formed an amorphous structure. In particular, this catalyst exhibited an overpotential of 206 mV at 150 mA cm −2, outmatching most non-noble OER catalysts reported so far; it also operates smoothly in various stability tests.
