we developed a one-step, template-free solvothermal method to synthesize Co3O4 hollow octahedra. The hollow Co3O4 octahedra that were prepared show a good pseudocapacitance when evaluated as an electrode material for supercapacitors. In particular, the Co3O4 hollow Octahedra exhibited a higher specific capacitance than the Co3O4 nanocubes, which was attributed to lower series and diffusive resistance. A test evaluating long-term stability revealed Good cycle performance of the Co3O4 hollow octahedra.
