In this study, FeCo2O4@Co3O4 bifunctional catalysts with a unique structure combining nanosheets and nanowires were prepared on nickel foam by a simple hydrothermal + annealing method. The catalysts exhibited excellent catalytic activity for hydrogen pro-duction during urea electrooxidation reaction (UOR) and ethanol oxidation reaction (EOR). For UOR, the potential at 10 mA/cm2 current density is 1.387 V and the tafel slope is 67 mV/ dec. In the configured two-electrode electrolytic cell, the FeCo2O4@Co3O4 catalysts in the UOR and EOR processes required only 1.425 and 1.471 V, respectively, to...
