在SMAD法制备的氧化铝负载钯催化剂上，通过分解乙炔合成了丝状碳纳米结构。用透射电镜分析了碳产物的结构。在500 ~ 700℃之间，主要结构为碳纳米纤维。在750 ~ 800℃之间，观察到碳产物的质量和体积显著增加。在此温度范围内，大部分碳以高质量的多壁碳纳米管的形式存在。（©2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim）
Filament‐like Carbon Nanostructures were synthesized by decomposition of acetylene over an alumina supported palladium catalyst prepared by the SMAD method. The structure of carbon products was analyzed by transmission electron microscopy. Between 500 and 700 °C the predominant structures were carbon nanofibers. Between 750 and 800 °C an important mass and volume increase of carbon products was observed. For this temperature range most of the Carbon was in the form of high quality multiwall carbon nanotubes.
