The reaction of MoO3 and S at temperatures higher than 300 degrees C in an argon atmosphere provides a convenient and effective method for the synthesis of MoS2 nanocrystalline substances. MoS2 nanotubes and fullerene-like nanoparticles have been obtained by the reaction at 850 degrees C under well-controlled conditions. The influences of reaction temperature and duration were carefully investigated in this paper. All of the nanostructures were characterized by Xray powder diffraction (XRD), transmission electron microscopy (TEM), and high-resolution transmission electron microscopy (HRTEM). A stepwise reaction model and rolling mechanism were proposed based on the experimental results.
在氩气气氛中,三氧化钼(MoO₃)与硫在高于300℃的温度下反应,为合成二硫化钼(MoS₂)纳米晶体物质提供了一种便捷有效的方法。通过在850℃且控制良好的条件下进行反应,已获得了MoS₂纳米管和类富勒烯纳米颗粒。本文仔细研究了反应温度和持续时间的影响。所有纳米结构均通过X射线粉末衍射(XRD)、透射电子显微镜(TEM)和高分辨率透射电子显微镜(HRTEM)进行了表征。基于实验结果提出了逐步反应模型和滚动机制。
