摘　　要：以乙醇为碳源,Ni-Fe/4分子筛为催化剂,采用化学气相沉积法制备碳纳米管(CNTs)。研究了反应温度和Ni/Fe摩尔比对CNTs管径的影响,反应温度对碳产率的影响。利用TEM和SEM观察CNTs形貌,结果显示,CNTs管径随着反应温度的升高和Ni/Fe摩尔比的降低而增大。Carbon nanotubes （CNTs） were prepared by chemical vapor deposition method using ethanol as a carbon source and Ni - Fe supported on 4 A molecular sieve as a catalyst. The influence of reaction temperature and Ni/Fe molar ratio on the outer diameter of CNTs, and effect of reaction temperature on yield of carbon was studied. The morphology of CNTs was investigated by SEM and TEM, The results showed that the diameter of creased with the increasing of the Ni/Fe CNTs increased with the increasing of temperature but demolar ratio.
