Fe,Ni bimetallic oxide nanomaterials (NiFe2O4) were successfully deposited on nickel foam substrate by cyclic voltammetric electrodeposition,and then prepared NiFe2O4/NF electrode.The morphology and structure of the nanomaterials were characterized by FE-SEM and XRD.Meanwhile,the electrocatalytic performances of the prepared NiFe2O4/NF electrode for oxygen evolution reaction (OER) in alkaline solution was tested by polarization curves and constant current electrolysis.The results indicated that the NiFe2O4/NF electrode exhibited excellent electrocatalytic performances for OER.The overpotential was 280mV for OER at the current density of 10mA/cm2 and the Tafel slope was 72.2mV/dec.Moreover,the overpotential changed slightly after constant current electrolysis for 2 hours.Compared with the current commercial IrO2 electrocatalyst,the overpotential of OER was reduced at high current density.
