摘　　要： 以MoO3粉和S为原料，高温下在普通管式炉中化学气相反应制备合成了MoS2纳米管。结果显示制备合成的MoS2纳米管全是开口的，直径分布很均匀，有的纳米管上粘结有纳米粒子。研究了实验温度、气流速度（反应气氛）对实验结果的影响，结果显示反应温度在810-905℃范围内才能生成MoS2纳米管；气流速度（反应气氛）如果不合适将生成MoO2或MoO2-xSx。在实验结果的基础上提出了逐步反应模型和一种新的MoS2纳米管形成机理。 MoS2 nanotubes are obtained by the chemical vapour deposition reaction from MoO3 powder and S in a conventional tube furnace at elevated temperature. It is shown that all of MoS2 nanotubes are openended with uniform diameters. Some nanotubes remain attached to nanoparticles. The influences of reaction temperature , argon flow rate （ reaction atmosphere） on products are studied. It is shown that nanotubes are prepared only at 810 -905℃ with an appropriate argon flow rate. MoO2 or MoO2-xSx is produced while argon flow rate are inaccurate. A stepwise reaction model and a newly growth mechanism of MoS2 nanotubes are proposed based on the experimental results.
