Formation of CMK-3/Co3O4 nanosheets on nickel foam with markedly enhanced pseudocapacitive properties
چکیده انگلیسی
Composites of mesoporous carbon (CMK-3) and Co3O4 nanosheets grown on nickel foam were successfully synthesized by a simple route. A bare Co3O4 film was synthesized for comparison. With the addition of CMK-3, the Co3O4 nanoparticles self-organize and agglomerate into nanosheets, showing a significant influence by CMK-3 on the morphology. The CMK-3/Co3O4 exhibits an optimal specific capacitance of 1131.3 F g−1 in 3 mol L−1 KOH aqueous electrolyte at 0.5 A g−1, and a retention ratio of 91% over 3000 cycles, both being much higher than that achieved from the bare Co3O4 film (727 F g−1 of specific capacitance, and 82% capacitance retention ratio), indicating that the CMK-3/Co3O4 nanosheets are very promising as electrode materials for supercapacitor applications.
