In this paper, single-crystal line Co3O4 hollow octahedral hollow cages with tunable surface aperture were synthesized by the carbon-assisted carbothermal method. On the basis of electron microscopic observation and structural analysis, all the following factors, including the precursor concentration, species of precursor, intrinsic crystal structure of products and carbon-assisted carbothermal reaction, play key roles in the formation Of Co3O4 octahedral hollow structures. When the as-prepared Co3O4 samples were used as the anode materials in lithium ion batteries (LIBs), it was found that the octahedral hollow cages with large surface aperture performed better than both those with small surface aperture and Co3O4 nanoparticles, indicating that not only the single-crystalline robust structure but also the tunable surface aperture in the shell could affect the electrochemical property in LIBs.
