摘要:

利用天然生物质杨絮特殊的管状结构通过简单的高温碳化法制备出碳微米管(CMTs). 将所得到的碳微米管作为基底, 采用化学气相沉积法制备出三维结构的碳微米管/碳纳米管(CNTs)复合材料. 利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射(XRD)光谱仪、拉曼光谱仪对其进行了详细分析. 通过两电极测试体系对其超级电容性能进行测试, 碳微米管/碳纳米管复合电极在1 mol·L-1Li2SO4电解液中的比电容值可达77 F·g-1, 远大于碳微米管的比电容值(23 F·g-1).

Abstract:

Carbon microtubes (CMTs) were prepared by the carbonization of poplar catkins according to their natural microtubular structure. The CMTs were then used as the substrate for growing carbon nanotubes (CNTs) by chemical vapor deposition. The prepared three-dimensional CMT/CNT composites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Raman spectroscopy. Two-electrode supercapacitor cells constructed with the CMT/CNT showed a specific capacitance of 77 F·g-1 with 1 mol·L-1Li2SO4 electrolyte, which is much higher than that for CMTs (23 F·g-1).

Key words: Carbon microtube, Carbon nanotube, Poplar catkin, Biomass, Supercapacitor
