这篇文章涉及用一种新的脉冲电弧放电技术合成单壁碳纳米管（SWCNT）。脉冲电弧放电是一种非常有趣的技术，因为它类似于用于合成SWCNT的众所周知的激光蒸发技术，并且应该允许扩大规模以达到SWCNT的批量生产。我们进行了许多实验，以找到基于电弧的SWCNT合成的最佳条件。所获得的数据进行了比较与已知的结果从激光蒸发合成单壁碳纳米管。结果表明，有可能获得与激光蒸发合成非常相似的电弧放电法的特定优化合成条件。这两种方法都允许获得类似的纳米管质量（高产率，窄直径分布）。我们讨论了这两种方法之间的形成机制的相似之处。（© 2007 WILEY‐VCH Verlag GmbH & Co.

This contribution deals with the synthesis of Single‐Walled Carbon Canotubes (SWCNT) with a novel pulsed arc‐discharge technique. Pulsed arc‐discharge is a very interesting technique because it is similar to the well‐known laser evaporation technique for the synthesis of SWCNT and should allow a scale‐up to reach a SWCNT volume production. We performed a number of experiments to find optimal conditions for the arc‐based SWCNT synthesis. The obtained data have been compared with known results from laser evaporation synthesis of SWCNT. The results indicate that it is possible to get specifically optimized synthesis conditions for the arc‐discharge method that are very similar to that of the laser evaporation synthesis. Both methods allow to get similar nanotube qualities (high yield, narrow diameter distribution). We discuss similarities in the formation mechanisms between both methods.
