多壁和单壁碳纳米管可以通过在还原性气氛中热解有机金属前体如双烯烃和酞菁来方便地制备。更重要的是，有机金属化合物单独或与烃的混合物的热解产生具有有用的场发射和储氢性质的对齐的纳米管束。通过在噻吩存在下热解有机金属化合物，大量获得Y-结纳米管。Y型结管在纳米电子学中具有良好的应用前景。由有机金属化合物制备的碳纳米管可用于制备其他材料如BN、GaN、SiC和Si（3）N（4）的纳米线和纳米管。
Multiwalled as well as single-walled carbon nanotubes are conveniently prepared by the pyrolysis of organometallic precursors such as metallocenes and phthalocyanines in a reducing atmosphere. More importantly, pyrolysis of organometallics alone or in mixture with hydrocarbons yields aligned nanotube bundles with useful field emission and hydrogen storage properties. By pyrolysis of organometallics in the presence of thiophene, Y-junction nanotubes are obtained in large quantities. The Y-junction tubes have a good potential in nanoelectronics. Carbon nanotubes prepared from organometallics are useful to prepare nanowires and nanotubes of other materials such as BN, GaN, SiC, and Si(3)N(4).
