摘要 用金属Mg、C2Cl6和AlCl3作原料,以苯为溶剂,在200℃下通过催化置换反应12小时,生成碳纳米管.产物用XRD、TEM、HRTEM和拉曼光谱来分析表征,产品为多壁碳纳米管,直径约为100nm左右,长度为几微米.通过对比实验证明lewis酸(AlCl3)在碳纳米管的形成中起了重要的作用,并提出了一种可能的反应机理.本方法也可用于制备其它碳质材料. Carbon nanotubes were synthesized via a catalyzed replacement reaction at 200℃ for 12h using metallic Mg, C2Cl6 and AlCl3 as starting materials and benzene as solvent. The products were characterized with XRD, TEM, HRTEM and Raman spectrum. The results showed that the products were hexaganol phase carbon nantubes with the average diameter of 100 nm and the length of several microns. It is supposed that the Lewis acid AlCl3 play important roles in the formation of carbon nanotubes by comparing experiments. A possible reaction mechanism was proposed. It may provide a new method to produce other carbonaceous materials.
