摘要
以二茂铁为催化剂、苯为碳源、噻吩为生长促进剂，采用气相催化热解法制备了纳米碳管，并运用TEM、Raman、XRD等对纳米碳管的外观形貌、结构、晶化程度等进行了观察研究。结果表明：在1155℃下能制备出管径20～100nm的纳米碳管，其最大产量是催化剂用量的350％。
Carbon nanotubes can be synthesized, using benzene as carbon feedstork, ferrocene as catalyst and thiphene as growth promoter, by gas-phase thermal catalytic decomposition. By using TEM, Raman and XRD, the morphology, structure and crystallinity of carbon nanitubes are studied. The result indicated that at 1550℃, carbon nanotubes with the diameter of 20 - 100nm can be produced. The maximal yield of carbon nanotubes is 350% the weight of the catalyst.
