Coating Method

Ordered mesoporous carbon nanospheres with uniformly penetrating channels have been successfully synthesized by a nanocasting method using mesoporous silica as a template. The ordered mesoporous carbon nanospheres were investigated as electrode materials for supercapacitors via high-resolution transmission electron microscopy, nitrogen adsorption and desorption isotherms and a variety of electrochemical testing techniques. The electrodes with ordered mesoporous carbon nanospheres prepared by coating method exhibited good rate capability and reversibility at high scan rates in electrochemical performances. Ordered mesoporous carbon nanosphere electrode with specific surface area of 904 m2/g maintained a stable specific capacitance of 210 F g-1under specific current of 0.1 A g-1for 500 cycles of charge/discharge.

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.
