Colloidal synthesis of iridium-iron nanoparticles for electrocatalytic oxygen evolution

Author affiliations

Abstract

The design of high-performance electrocatalysts for oxygen evolution reactions (OER) in acidic condition is highly desirable for the development of the proton exchange membrane (PEM)-based water electrolyzer. Herein, we report the colloidal synthesis of iridium-iron alloy nanoparticles with an average diameter of 2.4 nm. The as-synthesized IrFe alloy produces a current density of 10 mA cm−2 in acidic and alkaline conditions at overpotentials of 278 and 286 mV, respectively.
