以甲烷为碳源,N2和H2作载气,二茂铁作催化剂前驱体,采用流动催化热解法制备出大量高质量取向性好的多壁碳纳米管(MWCNTs)。利用扫描电子显微镜(SEM),透射电子显微镜(TEM)和Raman光谱对碳纳米管的形貌和结构进行了表征。该制备过程工艺简单并且成本低廉,对实现碳纳米管的规模生产具有重要意义。 Using MWCNTs, a large number of high quality oriented MWCNTs were prepared by flow catalytic pyrolysis using methane as carbon source, N2 and H2 as carrier gas and ferrocene as catalyst precursor. The morphology and structure of carbon nanotubes were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy. The preparation process has the advantages of simple process and low cost, and is of great significance for realizing the scale production of carbon nanotubes.
