Iron phosphide nanoparticles as an efficient electrocatalyst for the OER in alkaline solution

Ultrasmall iron phosphide nanoparticles have been reported as an efficient electrocatalyst for the oxygen evolution reaction under alkaline conditions with a lowoverpotential and Tafel slope. Mixing the FeP nanoparticles with reduced graphene oxide further reduces the overpotential to 260 mV at 10 mA cm(-2), which is one of the lowest values reported for OER electrocatalysts.
