采用高温脉冲电弧放电技术制备了单壁碳纳米管（SWNTs），该技术是近年来在本实验室发展起来的，与传统的稳态电弧放电方法相比，已有文献报道。扫描电子显微镜（SEM）和透射电子显微镜（TEM）的观察表明，烟灰中产生了大量的单壁碳纳米管束。单壁碳纳米管的脉冲电弧制备需要高温（≥1000°C）、长脉冲（≥1ms）和重稀有气体（如Ar或Kr）作为缓冲气体。
Single-wall carbon nanotubes (SWNTs) have been produced for the first time using the high-temperature pulsed arc-discharge technique, which has been developed recently in this laboratory, as reported in the conventional steady arc discharge method. Scanning electron microscopic (SEM) and transmission electron microscopic (TEM) observations reveal significant production of bundles of SWNTs in soot. The pulsed arc production of SWNTs favors a high-temperature (≥1000°C), long pulses (≥1 ms) and a heavy rare gas such as Ar or Kr as a buffer gas.
