Abstract Tubular Co3O4 nanostructures were prepared from cobalt nanowires embedded in an anodic alumina template. The morphologies of nanowires/nanotubes were studied by transmission electron microscopy, and x-ray diffraction was used in the analysis of the nanostructures and phases. A possible formation mechanism of the process from nanowires to nanotubes is discussed. The vibrating sample magnetometer measurements show anomalous magnetic behaviour of the cobalt oxide nanotubes at low temperature.
