摘要：

Nanowires (Co3O4 and NiCo2O4) and nanoplates (beta-Ni(OH)(2)) grown on Ni foam are successfully prepared by a template-free method and used as cathode electrodes for the electroreduction of H2O2 in an alkaline medium. Catalytic performance is investigated via cyclic voltammetry and chronoamperometry. The Co3O4 and NiCo2O4 nanowire electrodes exhibit much better catalytic activity, stability, and mass transfer properties for H2O2 electroreduction than pressed Co3O4 and NiCo2O4 nanoparticle/carbon/PTFE electrodes. A current density of 101.8 mA cm(-2) and 122.7 mA cm(-2) are respectively achieved on Co3O4 and NiCo2O4 nanowire electrodes at -0.4 V in 0.4 mol/L H2O2 and 3.0 mol/L NaOH solution at room temperature.
