摘要
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。
Methane was used as carbon source , nitrogen and hydrogen as carrier gas, and ferroeene as catalyst precursor to prepare high-quality aligned multiwalled carbon nanotubes at 850℃ by the floating catalytic pyrolysis method. And their morphology and structures were characterized by scanning electron microscopy, transmission electron microscopy and Raman spectrum. This synthesis technique shed light on large-scale synthesis of carbon nanotubes for its simplified processing and low-cost.
