| Abstract: | Mesoporous carbon has been synthesized using nano-CaCO3 as a template and sucrose as carbon precursor. It is shown that the CaCO3/sucrose weight ratio has a marked effect on the porosity of the carbon. At a weight ratio of CaCO3/sucrose of 1:1, the surface area of the carbon reaches 892 m2 g−1 and the pore size is around 45 nm. The carbon shows a capacitance of 155 F/g with excellent rate capability in 6 mol L−1 KOH aqueous electrolytes. |
