Preparation of Quaternary FeCoMoCu Metal Oxides for Oxygen Evolution Reaction
Molybdenum doping is an effective way to improve the oxygen evolution reaction(OER) properties of catalysts, which can efficiently improve the electronic conductivity, mass transport process, and intrinsic activity of transition metal oxides or hydroxides, especially for those multi-component oxides with more abundant active sites. Herein, we have prepared a quaternary FeCoMoCu metal oxide on Cu foam(FeCoMoCuO x@Cu) as an efficient OER catalyst. As expected, FeCoMoCuO x@Cu could exhibit a low overpotential(252 mV at the current density of 10 mA/cm2) and exceptional stability(10000 cycles of CV scans or constant electrolysis for 48 h).
