摘要
以二茂铁和二甲苯为原料在Ar和H2 气氛中不同温度下热解制备出了不同直径分布的碳纳米管。在 740℃、780℃、82 0℃和 880℃下制备出的碳纳米管的外径分布分别为 1 7-80nm、2 0 - 73nm、40 - 70nm、1 7- 2 7nm。拉曼光谱和透射电子显微镜 (TEM )观察表明 ,在82
Carbon nanotubes with different diameter distributions have been produced by thermal decomposition of a ferrocene-xylene mixture under different temperatures in an Ar/H 2 atmosphere. The diameter ranges of the carbon nanotubes produced under 740, 780, 820 and 880℃ are 17-80nm, 20-73nm, 40-70nm and 17-27nm, respectively. Both TEM and Raman studies show that carbon nanotubes with best crystallinity are produced under 820℃.
