The nickel oxide microtubes with high surface-to-volume ratio have been achieved using the Bacillus subtilis bacteria. Surface properties of the metal-oxide nanostructured materials were investigated by electron microscopy. The surface area of that was also studied by the Brunauer-Emmett-Teller analysis method. The materials were used at the construction of supercapacitor as an electrode active material.
