采用有序中孔硅为模板成功合成了排列有序的炭纳米棒阵列OCNR.XRD测试和TEM观测表明,OCNR为有序排列(p6mm)的炭纳米棒阵列构成.N2吸脱附测试表明,OCNR具有典型的中孔结构和集中的中孔分布.与超大比表面积的活性炭Maxsorb相比,OCNR具有更好的电容特性,更高的功率输出和优异的高频电容性能,这都得益于OCNR规整的孔道有利于电解质水合离子的快速扩散.循环伏安研究表明,在50mV/s的高电压扫描速度下,OCNR的比电容值仍可保持在166F/g,而此时Maxsorb的比电容值却降低到73F/g.值得一提的是,OCNR在提供高功率输出的同时,仍能保持高的能量密度,可以应用于对功率输出和能量密度都有较高要求的场合.
The ordered mesoporous carbon nanorod array (OCNR) was successfully synthesized using ordered mesoporous silica as a template.XRD and TEM observations show that the OCNR is composed of ordered carbon nanorods (p6mm) OCNR has a typical mesoporous structure and a concentrated mesopore distribution.Compared with Maxsorb with large specific surface area, OCNR has better capacitance characteristics, higher power output and excellent high-frequency capacitance performance, thanks to The regular channel of OCNR is conducive to the rapid diffusion of electrolyte hydrate ions.The cyclic voltammetry study shows that the specific capacitance of OCNR remains at 166 F / g at a high voltage scan rate of 50 mV / s, while the specific capacitance of Maxsorb The value is reduced to 73 F / g. It is worth mentioning that OCNR can maintain high energy density while providing high power output, and can be applied to applications that require high power output and energy density.
