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 low overpotential 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. Ultrasmall FeP nanoparticles have been reported as an efficient oxygen evolution electrocatalyst in alkaline medium with low onset potential for oxygen evolution and require low overpotential to reach 10 mA cm −2 exchange current density.
