摘要
开发以煤气为碳源采用化学气相沉积法制备单壁碳纳米管,并对其作为超级电容器电极的电化学性能进行研究。通过电子扫描电镜、电子透射电镜、拉曼光谱以及X射线衍射等手段对产品的形态、结构及性质进行表征分析,并对单壁碳纳米管的生长机理进行讨论;分别通过循环伏安、恒压充放电实验对单壁碳纳米管电极进行电化学性能分析。
Single- walled carbon nanotubes have been prepared from coal gas by catalytic chemical vapor deposition technique with ferrecene as catalyst, and electrochemistry analysis was carried on supercapacitance using nanotubes as electrodes. The SWNTs products were characterized by scanning electron microscopy, transmission electron microscopy, X - ray diffraction and Raman spectroscopy. The growth mechanism of the SWNTs derived from coal gas was discussed in terms of the catalyst property and the coal gas composition. Specially, the capacitance prope^es of electrodes of CNTs were studied by cycle volt-ampere and galvanotactic charge/discharge technique in two- electrode carbon/ carbon cells in detail.
