碳纳米管由于其独特的结构和优异的电学、光学、力学、热学等物理化学性能,在材料、电子器件、传感器、催化剂和能源等领域具有广泛的应用前景,但是如何低成本批量制备高品质的碳纳米管是实现碳纳米管大规模应用的关键。本文综述了近年来化学气相沉积法合成碳纳米管的研究进展,表明化学气相沉积法是大规模可控制备碳纳米管最有效的方法,并对其未来的发展方向进行了分析和展望。

Carbon nanotubes have unique nanostructures and remarkable electrical, optical, mechanical, thermal as well as other physicochemical properties, which make them suitable for a wide range of applications as materials, electronic devices, chemical sensors, catalysts, energy and so on. However, the large-scale synthesis of high quality carbon nanotubes with low cost is the most important to realize its industry applications. The recent progress in synthesis of carbon nanotubes by chemical vapor deposition is detail reviewed. It is indicated that chemical vapor deposition is the most efficient technique for the controllable preparation of carbon nanotubes in large-scale, and the development direction of structure-controlled growth of carbon nanotubes in the future is also addressed.
