| 摘要: 利用法国梧桐絮(花粉)的管状结构，通过简单的碳化处理制备了碳微米管。并用扫描电子显微镜、X-射线衍射光谱仪、拉曼光谱仪和X射线光电子能谱仪对碳微米管进行了详细分析。碳微米管的外径为20~30 μm，壁厚约为1 μm。其内外壁存在着许多微孔和介孔，BET比表面积为265 m2·g-1。碳微米管具有典型的电化学双电层电容性能，表现出优异的稳定性，展示了在超级电容器方面的应用潜力。 | |

| Abstract: The fluff (flower pollen) of chinar tree was carbonized to prepare carbon microtubes (CMTs) due to their natural micro-tubular structure. The as-prepared CMTs were well characterized by scanning electron microscopy, X-ray diffraction, Raman spectroscopy and X-ray photoelectron spectroscopy. The outer diameters of CMTs are in the range of 20~30 μm and the wall thickness is about 1 μm. Many micro- and meso-pores exist in their outer and inner walls, and the Brunauer-Emmett-Teller (BET) surface area is 265 m2·g-1. The CMTs were demonstrated to show a typical characteristics of electrochemical double layer capacitance, indicating their potential in supercapacitors. | |
