Using ethyne as source gas, CNTs were successfully synthesized by CVD method. By comparing different synthesis technics, the influences of parameter to the grow of CNTs, such as catalysts, growth time, reaction temperature and ratio of all kinds of carrier gases were investigated. The results showed that the influence of carrier gas, reaction temperature, and the growth time on synthesis of CNTs was significant. In conclusion, a better condition for carbon nanotube growth was obtained. Through analyzing Raman Spectrum of samples, GM and SWNTs' characteristic peak-RBM was indicated.

采用乙炔为碳源、氢气和氩气为载气，利用气相催化热解法在AAO模板上成功的制备出了纳米碳管，用TEM，SEM，EDS，Raman等表征方法研究了生长温度、裂解时间、载气含量和不同催化剂对碳纳米管的石墨化程度、产物形态的影响，指出了单壁碳纳米管的特征振动模式—径向呼吸振动模以及拉伸振动模式G模，缺陷导致的D模，并采用蒸金后的样品进行了场发射的测试，得到了F-N曲线，与理论符合较好。
