摘要
High-quality carbon nanotubes （CNTs） are promising materials in many applications. However, current chemical vapor deposition （CVD） methods for CNT synthesis suffer from the discrepancy between the quality and yield of CNTs： Low-quality CNTs can be synthesized with high yield, while high-quality CNTs can only be synthesized with low yield. Here a CVD method has been designed to synthesize both high-quality and low-quality CNTs using the same combination of catalyst and precursor. As a result, we were able to understand the reasons for the low yield in high-quality CNT synthesis and a method was derived to improve their yield. This understanding is an important step towards high- yield synthesis of high-quality CNTs.
高质量的碳 nanotubes (CNT ) 在许多应用正在答应材料。然而，为 CNT 合成的当前的化学蒸汽免职(CVD ) 方法受不了在 CNT 的质量和收益之间的差异：低质量的 CNT 能与高产量被综合，当高质量的 CNT 能仅仅与低产量被综合时。这一个 CVD 方法被设计了高质量、低质量的 CNT 使用综合催化剂和先锋的一样的联合。作为结果，我们能理解为在高质量的 CNT 合成和一个方法的低收益的原因被导出改进他们的收益。这理解是向高质量的 CNT 的产量很高的合成的重要的步。
