An iron oxide decorated nickel iron alloy nanoparticle/porous graphene hybrid exhibits high electrocatalytic activity and excellent durability toward oxygen evolution reaction (OER). It displays a low overpotential of 274 mV at 10 mA cm(-2), and low Tafel slope of 37 mV dec(-1), showing a superior performance to the state-of-the-art RuO2 OER electrocatalyst.
