We developed a facile synthetic route of porous cobalt oxide (Co{sub 3}O{sub 4}) nanorods via a microemulsion-based method in combination with subsequent calcination process. The porous structure was formed by controlled decomposition of the microemulsion-synthesized precursor CoC{sub 2}O{sub 4} nanorods without destruction of the original morphology. The as-prepared Co{sub 3}O{sub 4} nanorods, consisting of small nanoparticles with diameter of 80-150 nm, had an average diameter of 200 nm and a length of 3-5 {mu}m. The morphology and structure of synthesized samples were characterized by transmission electron microscopy and scanning electron microscopy. The phase and composition were investigated by X-ray powder diffraction and X-ray photoelectron spectroscopy. The optical property of Co{sub 3}O{sub 4} nanorods was investigated. Moreover, the porous Co{sub 3}O{sub 4} nanorods exhibited high electrochemical performance when applied as cathode materials for lithium-ion batteries, which gives them good potential applications. - Graphical abstract: The porous Co{sub 3}O{sub 4} nanorods synthesized via a microemulsion-based method in combination with subsequent calcination were applied in the negative electrode materials for lithium-ion batteries and exhibited high electrochemical performance.
