A series of ordered mesoporous carbon/cobalt oxide composites as electrode materials for supercapacitor were prepared via incipient wetness impregnation method. The results show that the structure and electrochemical properties of the composites depend mainly on the cobalt oxide loading amount in the ordered mesoporous carbon. The optimum loading amount of cobalt oxide is found to be 30 wt.%, and the composite derived from which exhibits 283.52 F/g of specific capacitance at the scan rate of 5 mV/s. The specific capacitances of which are higher than that of OMC and pure Co3O4 at every given scan rate, showing good synergetic effect.

In this article, well–dispersed cobalt oxide nanoparticles supported on mesoporous carbon (CMK–3) have been successfully synthesized. The composites were characterized by field emission scanning electron microscopy, transmission electron microscopy, X–ray diffraction and nitrogen adsorption–desorption analysis. The results have confirmed that, at a cobalt loading of 15 wt%, the composites have not only retained mesoporous structure of the support but also shown a good control of dispersed cobalt oxide nanoparticles with size of ~4 nm. The electrochemical property tests for the synthesized samples have shown significant improvement compared to the blank carbon (CMK–3) without cobalt oxide incorporation.
