摘要： 采用热化学气相沉积(TCVD)法裂解酞菁铁(FePc)和乙烯(C2H4)制备出高210 μm的取向碳纳米管阵列(ACNTA). 用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、拉曼光谱和X射线光电子能谱(XPS)对制备的样品进行了表征, 系统研究了反应温度、反应时间、C2H4流量对ACNTA生长的影响. 结果表明, 样品具有高取向性且纯度高. 800 ℃是裂解FePc和C2H4制备ACNTA的最优温度, 催化剂的活性可以保持较长时间(60 min), 通入C2H4促进了ACNTA的快速生长, 最适合流量为50 cm3/min.

Abstract: Aligned carbon nanotube arrays(ACNTA) with 210 μm in length were prepared by pyrolysis of iron(Ⅱ) phthalocyanine(FePc)and ethylene(C2H4). The as-grown ACNTA, which were well-aligned and pure, were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), Raman spectrum and X-ray photoelectron spectroscopy(XPS). The influence of experimental conditions, such as temperature, growth time, and flow rate of C2H4 on the formation of ACNTA were systematically investigated. The results indicate that 800 ℃ was the most suitable temperature for the preparation of long ACNTA by pyrolysis of FePc and C2H4 , the activity of catalyst could be kept for a rather long time(60 min), the addition of C2H4 significantly enhanced the growth speed of ACNTA and 50 cm3/min was found to be the optimal flow rate for the formation of ACNTA.
