Abstract

Sluggish kinetics in the reaction of water splitting is the major obstruction. Design and development of noble metal-free, active and bifunctional electrocatalysts are crucial for the oxygen evolution reaction (OER). Transition-metal selenides have been applied to be OER catalyst alternatives to noble metal-based catalysts. Herein, we report that a Fe-doped Ni3Se2 film electrodeposited on a conductive three dimensional macro-porous Ni foam (NF) substrate behaves as a robust electrocatalyst for OER in strongly basic media (1 M, KOH), with good activity over a un-doped counterpart. This catalyst showed excellent performances, exhibiting a 10 mA cm-2 current density at an overpotential of 225 mV and low Tafel slope (35.3 mV dec-1), indicating an enticing prospect in OER.
