Abstract

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.

Keywords: electrocatalysis; laser induced graphene; oxygen evolution reaction; polymers; supramolecular chemistry.
