Ordered Porous

Ordered mesoporous carbon film supporting vanadium oxide nanoparticles has been synthesized via ultrasound-assistant impregnation method with ordered mesoporous carbon C-FDU15 film as the host and V 2 O 5 sol as the guest precursor. The hybrids exhibit type IV sorption isotherms with H2 hysteresis loop, indicating the well-retained characteristics of ordered mesoporous structure. The capacitance of the materials is enhanced with V 2 O 5 loading. Particularly, the hybrids with 32.26 wt.% V 2 O 5 loading yield an important capacitance of 128 F/g in 1 mol/L KNO 3 electrolyte under a potential range from -0.6 V to 0.6 V. The improved specific capacitance of the hybrids is proposed to be the combination of the double-layer capacitance of ordered porous structure and the pseudocapacitance derived from V 2 O 5.

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.
