This work was performed in collaboration with Prof. Guangzhi Hu from the University of Chinese Academy of Sciences. Here we report the microwave-assisted synthesis of Mo-doped FeNi3 nanoparticles as excellent oxygen evolution electrocatalyst. Our results were published in the journal of Electrochemistry Communications.

Oxygen evolution reaction (OER) plays a pivotal role in water-splitting. Here, we report a facile method to synthesize multimetal supported on commercial carbon black via a time-saving microwave process. Crystalline FeNi3 nanoparticles homogeneously doped with Mo are formed via a microwave treatment and activated to metal oxyhydroxide in-situ during cyclic voltammetry test with overpotential of only 280 mV at 10 mA cm− 2 for OER in alkaline electrolyte, outperforming RuO2. Our synthesis methodology is a promising alternative for large-scale production, delivering a valuable contribution to catalyst preparation and electrocatalytic water oxidation research.
