【摘要】 利用扩散火焰合成碳纳米管是一项新的技术和方法。本文介绍了这种新方法的基本原理,较系统地研究了火焰参数、基板材料、合成时间等对碳纳米管形态的影响。初步研究表明它在无外加催化剂的情况下也能合成碳纳米管,具有“自生催化”的特点。更多还原

【Abstract】 Carbon nanotubes synthesis using diffusion flame is a kind of novel technique. In this paper, the basic principle of the method was introduced, and the influence of parameters) such as flame, base materials, time, etc. on the formation and morphology of carbon nanotubes was discussed. The experiments showed that carbon nanotubes could be obtained without "seed", called "autocatalysis or unseeded catalysis".更多还原
