In this communication, we demonstrate the development of a MnCo2S4 nanowire array directly grown on Ti mesh (MnCo2S4 NA/TM) as an electrocatalyst for the oxygen evolution reaction in 1.0M KOH which only needs an overpotential of 325 mV to drive 50 mA cm(-2). At an overpotential of 500 mV, this electrocatalyst achieves a high turnover frequency of 0.81 mol O-2 per s.
