中文摘要：

排列的碳 nanotubes (CNT ) 被 organometallics 的答案的 nebulized 水花热分解在碳先锋溶剂综合。包括 n 戊烷， n 己， n-heptane 和 n 辛烷的直链的链烷的四种类型为排列 CNT 的合成被用作先锋溶剂。从扫描电子显微镜学，传播电子显微镜学和拉曼光谱学的结果证明从他们获得的 CNT 有 graphitization 的不同直径和度。n-heptane 对生长最合适，这被发现与高质量和收益联盟。象煮点和形成热含量那样的先驱的碳来源的热力学的性质被认为在 CNT 的合成起一个明确的作用。它将对以相对低的成本的排列 CNT 的可控制的准备很有用。

英文摘要：

Aligned carbon nanotubes（CNTs）were synthesized by nebulized spray pyrolysis of solutions of organometallics in carbon precursor solvents.Four types of straight-chained alkanes including n-pentane,n-hexane,n-heptane and n-octane were used as precursor solvents for synthesis of aligned CNTs.The results from scanning electron microscopy,transmission electron microscopy and Raman spectroscopy show that the CNTs obtained from them have different diameters and degrees of graphitization. It is found that the n-heptane is the most suitable for the growth of aligned CNTs with high quality and yield.The thermodynamic properties of precursory carbon sources such as boiling point and formation enthalpy are considered to play a decisive role in the synthesis of CNTs.It will be very helpful for the controllable preparation of aligned CNTs at relatively low cost.
