| 摘 要： | 首先利用硬模板法制备出介孔碳/石墨烯复合材料,然后向复合材料中引入具有赝电容活性的醌类分子进一步增大材料的电容性能。研究结果表明,负载30%(w/w)叔丁基氢醌的介孔碳/石墨烯复合材料具有最佳的电容性能,在电流密度为0.5 A·g~(-1)时,比电容值为355 F·g~(-1);当电流密度高达30 A·g~(-1)时,其比电容值高达226 F·g~(-1),比电容保持率为64%,表现出良好的速率特性。

| Abstract: | Mesoporous carbon/graphene composite was firstly synthesized by hard-template method. Then, different quinone molecules were introduced to improve the capacitive performance of the composite. The results show that mesoporous carbon/graphene composite with 30% (w/w) loading of butylhydroquinone shows the best capacitive performance. This sample exhibits specific capacitance of 355 and 226 F·g-1 at the current density of 0.5 and 30 A·g-1, respectively, highlighting its good rate performance. |
