Abstract

The electrodes of Ni foam supported NiCo₂O₄ nanowires were prepared by hydrothermal method, followed by a thermal treatment in air, and were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). It was found that the NiCo₂O₄ nanowires had a diameter of about 50 nm with a length up to 3 ~ 5 μm. The catalytic performances of the Ni foam supported NiCo₂O₄ nanowires for H₂O₂ electrooxidation were studied by cyclic voltammetry and chronoamperometry. The results show that the Ni foam supported NiCo₂O₄ nanowires electrode exhibited superior activity, stability, and mass transport property for H₂O₂ electrooxidation. A current density of 380 mA·cm ^-2 was achieved at 0.3 V in 0.4 mol·L ^-1 H₂O₂ and 2 mol·L ^-1 NaOH at room temperature.
