| Preparation of Hierarchical Porous Carbon and Its Application in EDLC |

| 摘要: 采用有机-有机自组装法和化学活化法相结合，制备了分级孔炭电极材料(HPC)。氮气静态吸附测试表明，化学活化使介孔炭的孔壁上产生了大量的微孔，从而使其比表面积大大增加。与以硬模板法制备的有序介孔炭(OMC)相比，HPC比OMC具有更为优异的电化学性能，这是因为微孔和介孔直接相连的分级孔结构，不仅增大了比表面积，而且能够显著减小电解质离子在电极材料孔道内的扩散阻力。 |

| Abstract: Hierarchical porous carbon was prepared by organic-organic self-assembly coupled with post-activation. As demonstrated by N2 adsorption tests, micropores were generated within the mesopore wall of MC via chemical activation, leading to dramatic increase of specific surface area. Compared to hard-templated ordered mesoporous carbon(OMC), HPC showed better electrochemical performances, which were ascribed to its unique micro-meso hierarchical porous structure that not only increases its surface area, but also decreases the diffusion resistance of electrolyte within the pore channels. |
