Abstract:

A new type of superior activity and highly cost-effective amorphous electrocatalyst Co-Mo-Fe on nickel foam (NF) supports is prepared by facile one-step rapid electrodeposition. The amorphous electrocatalyst Co-Mo-Fe/NF shows excellent oxygen evolution reaction (OER) performance, with a small overpotential of 218 mV at 10 mA cm-2 current density in 1 M KOH. It only needs overpotential of 252 mV at 50 mA cm-2 current density in 1 M KOH, and the Tafel slope is 45 mV dec-1. The results show that the doping of Fe significantly improves the oxygen evolution capacity of the Co-Mo-Fe system. The synergistic effect of the three metals and the doping of the third metal iron make the oxygen evolution active sites of the whole system increase significantly. This provides a feasible direction for the oxygen evolution reaction of cobalt transition metal.
