Cobalt oxide hollow microspheres with micro- and nano-scale composite structure: Fabrication and electrochemical performance
Abstract
Co{sub 3}O{sub 4} hollow microspheres with micro- and nano-scale composite structure self-assembled by nanosheets were successfully fabricated by the template-free wet-chemical approach. This method is simple, facile and effective. The Co{sub 3}O{sub 4} hollow microspheres with good purity and homogeneous size were well characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform IR (FTIR), thermogravimetric analysis (TGA) and inductively coupled plasma atomic emission spectrometer (ICP). The formation mechanism was deeply studied. The micro- and nano-scale composite structure constructed by the porous nanosheets promotes to improve the electrochemical properties of Co{sub 3}O{sub 4} hollow microspheres. The high discharge capacity of 1048 mAh g{sup -1} indicates it to be the potential application in electrode materials of Li-ion battery. - Graphical Abstract: Co{sub 3}O{sub 4} hollow microspheres self-assembled by nanosheets are successfully fabricated by a template-free wet-chemical approach.
