In this communication, we report the first use of commercial nickel iron (NiFe) foam as a novel three-dimensional anode for oxygen evolution reaction in alkaline electrolyte. The NiFe foam electrode exhibits onset overpotential of 300 mV and affords current density of 10 mA cm(-2) at an overpotential of 320 mV, with catalytic activity being maintained for at least 10 h. Further acid etching of this electrode leads to greatly enhanced OER activity. Copyright (C) 2015, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
