摘要：Electrochemical oxygen evolution reaction (OER) is hampering the development of hydrogen production on a large scale, accompanied with difficulties in achieving high current density (>1 A cm-2) and poor stability for current catalysts. Herein, the FeCoW hydroxides supported on Ni foam (FeCoW/NF) are synthesized via a simple and control-lable electrodeposition method, which deliver the high current density of 1.28 A cm-2 at the 770-mV overpotential vs reversible hydrogen electrode (RHE), together with steady oper-ation at 100 mA cm-2 for 100 h in 1 M KOH. Moreover, the as-prepared FeCoW/NF elec-trocatalyst possesses an ultralow overpotential of 360 mV vs RHE to drive oxygen evolution reaction for the current density of 100 mA cm-2, outperforming most current transition metal-based catalysts. This work enables opportunities in exploring promising paths to achieve non-noble electrocatalysts for scale-up water spitting at industrial current. & COPY; 2023 Hydrogen Energy Publications LLC.
