| 摘要: |
Mesoporous carbon spheres with a bimodal pore size distribution were prepared by suspension polymerization and steam activation method using phenol–formaldehyde resins as a carbon precursor. The asprepared carbon spheres had a specific surface area of 1006 m2 g 1, total pore volume of 1.34 cm3 g 1, mesoporous ratio of 81.3% and average pore size of 5.33 nm. Moreover, the carbon material showed a bimodal pore size distribution (3.5 and 23.8 nm). We found a high specific capacitance of 147 F g 1 for the carbon spheres in ionic liquid 1-ethyl-3-methylmidazolium tetrafluoroborate ([EMIm]BF4) at a current density of 2 mA cm 2 and small impedance at the interface of electrode/electrolyte. In addition, a specific energy of 20 Wh kg 1 at a specific power of 3100Wkg 1 was obtained in some particular cases. |
