In this study, Co3O4 nanostructured porous microtubes were prepared via chemical precipitation onto Aquaspirillum bengal bacteria in an aqueous solution. The morphological properties of the synthesized material were studied using a scanning electron microscopy (SEM). The diameter of the Co3O4 micro tubes is approximately 0.8 mu m, and the length is 4 mu m. The Brunauer-Emmett-Teller (BET) surface area was determined to be 87.07 m2/g. The nitrogen adsorption and desorption isotherm displayed properties associated with a typical type IV isotherm. The electrochemical properties of the produced material were studied using cyclic voltammetry (CV), long-term charge/discharge analysis and impedance spectroscopy (EIS).
