Enhanced electrocatalytic activity of water oxidation in an alkaline medium via Fe doping in CoS2 nanosheets

Author affiliations

Abstract

The development of new electrocatalysts is critical for efficient water electrolysis to produce hydrogen. In this communication, we report a novel electrocatalyst for the oxygen evolution reaction (OER) which is realized via Fe doping in CoS2 nanosheets (Fe–CoS2). This catalyst shows an overpotential of 302 mV for a current density of 10 mA cm−2, 85 mV less than that for CoS2. In addition, Fe–CoS2 also exhibits high catalytic stability.
