摘　　要：采用爆炸辅助化学气相沉积技术,以煤间接液化产物中的粗制石蜡为碳源制备碳纳米管.考察了催化剂前驱体和炸药填充密度对产物中碳纳米管形貌和纯度的影响,发现金属Co催化剂,炸药填充密度为0.2 g/mL时产物中碳纳米管的含量可达70%.在此基础上,尝试了利用另外两种重质碳源煤焦油和煤沥青合成碳纳米管.结果表明,利用重质碳源通过爆炸辅助气相合成碳纳米管是可行的,但是针对不同种类的碳源条件有待于进一步优化.Carbon nanotubes can be synthesized via detonation-assisted chemical vapor deposition using olefin, which is one of the products of indirect coal liquefaction from coal, as carbon source. After investigating influences of metal catalysts and explosive packing densities on structures and morphologies of the detonation products, it was found when the explosive packing density is 0.2 g/mE the nanotube＇s content of product using cobalt as catalyst is 70%. On this base, the synthesis of carbon nanotube using the other two heavy mass carbon sources is studied. The results show the conditions of synthesis via detonation-assisted chemical vapor deposition of carbon nanotubes need be further optimizing.
