摘要

Porous cobalt oxide (Co3O4) microplates have been successfully synthesised via a facile thermal decomposition from plate-like cobalt oxalate complex precursors. The microstructures and morphologies of the obtained Co3O4 materials are characterised by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and N-2 adsorption-desorption techniques. The characterisation results show that the obtained Co3O4 microplates are composed of plate-like polycrystalline nanoparticles with lengths of similar to 20 nm and widths of similar to 10 nm. In addition, these nanoplates aggregate each other to form the porous network with an average pore size of similar to 18.9 nm. The obtained porous Co3O4 microplates exhibit high discharge-charge capacities and good rate performances, suggesting a promising application as anode materials for Li ion batteries.
