Using a simple hydrothermal procedure and the subsequent annealing treatment, one-dimensional (1D) cobalt oxide nanowires (Co3O4-NWs) with tunable size have been successfully in situ fabricated on three-dimensional (3D) carbon foam (CF) network. By changing hydrothermal treating time (0.5, 1, 2 h) at 180 °C, size-controlled Co3O4 nanowires can be formed on the CF. Scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM) measurements showed that nanoporous Co3O4 nanowires are uniformly grew on the 3D carbon framework. Due to the three-dimensional porous architecture and the high conductivity of the carbon foam skeleton, the obtained composites possess fast mass transport, large surface area and high electronic conductivity, which make them very promising as electrochemical sensing materials. Among the studied composites, the Co3O4-NWs/CF hydrothermally treated for 1 h exhibited the lowest detection limit (1.4 μM) and the largest linear ranges (0.01 – 1.4 mM) and sensitivity (230 nA μM?1 cm?2) for H2O2 detection. The present study shows that metal oxides supported on 3D carbon materials present a class of promising sensing platform for electrochemical detection of H2O2.
