| 摘 要： | 利用透射电子显微镜和拉曼光谱方法研究了水对800℃下Ar气中催化分解CH4制备单壁碳纳米管（SWCNTs）的影响.结果表明，反应气中少量水（室温下反应气的湿度约5%）的引入提高了产物中SWCNTs的含量.初步分析认为，水在反应过程中起到了提纯作用，从而降低无定形碳生成率.此外，还发现水的引入缩小了产物中SWCNTs的管径分布.

| Abstract: | The effects of H2O on the synthesis single wall carbon nano tubes(SWCNTs)by decomposing CH4 in Ar at 800℃ were studied by TEM and Raman scattering. It is shown that the water existing in the reacting gas increases the percentage composition of the SWCNTs in the products. Preliminary analyses indicate that the water is involved in the purification course, and the generation of the amorphous carbon is brought about. Furthermore, the water can affect the distribution of the SWCNTs'diameter. |
