| 摘要: | 纳米碳材料被广泛应用于能量存储和催化等领域, 但简便而有效地制备高性能碳材料仍是一个挑战. 本文采用微波法制备爆米花, 经过预碳化、KOH活化后得到高比表面积和高微孔率的氮掺杂纳米碳材料, 并利用SEM、TEM、XRD、Raman、XPS和N2物理吸附表征材料的结构和组成, 并将其用作超级电容器电极材料. 结果表明: 活化样品由于具有发达的孔结构和合适的氮含量而具有优异的电化学性能; 在0.2A?g-1的电流密度下, 比电容高达214F?g-1; 当电流密度20A?g-1时, 其倍率性能保持65%. |
| Abstract: | Nanocarbon materials are widely used in energy storage, catalysis and other important fields. It still poses a great challenge to preparing the high-performance carbon materials via a facile and efficient method. The nitrogen doped microporous nanocarbon materials with high specific surface area are conveniently acquired by carbonization of popcorn prepared by microwave method and subsequent KOH activation. The materials are characterized by SEM, TEM, XRD, Raman, XPS and nitrogen physisorption, which are used as the electrode materials of supercapacitor. The results indicate that the satisfactory electrochemical performance of activated sample is owing to the well-developed pore structure and the suitable nitrogen content. The specific capacitance of the activated sample at the current density of 0.2A?g-1 can be as high as 214F?g-1, and the rate performance is maintained at 65% when the current density is kept at 0.2~20 A?g-1. |
