我们报道了利用（NH4）2MoS4在油胺中的原位热分解，在碳纳米纤维（CNFs）和多壁碳纳米管（CNTs）上沉积薄纳米层MoS2材料。采用x射线衍射（XRD）、透射电镜（TEM）、电子能量损失谱（EELS）和拉曼光谱对合成的MoS2@CNF和MoS2@CNT纳米复合材料进行了表征。TEM结果表明，CNFs和CNTs为二硫化钼纳米层的沉积和生长提供了良好的模板。在cnf上形成2-5层厚的MoS2纳米晶体，宽度为5-10 nm，而在CNTs上形成相同宽度的单层。应用的合成方法的优点是，它提供了对材料形态的控制，导致cnf和CNTs均匀和完全覆盖，没有单独的材料形成远离碳。据我们所知，在CNFs上沉积MoS2在其他地方还没有报道。
We report on the deposition of thin nanolayers of MoS2 material on carbon nanofibers (CNFs) and multiwalled carbon nanotubes (CNTs) by in situ thermal decomposition of (NH4)2MoS4 in oleylamine. The synthesized MoS2@CNF and MoS2@CNT nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), electron energy loss spectroscopy (EELS), and Raman spectroscopy. TEM results indicate that CNFs, as well as CNTs, provide an excellent template for the deposition and growth of MoS2 nanolayers. 2–5 layers thick MoS2 nanocrystals and 5–10 nm wide form on the CNFs, while monolayers of the same width form on the CNTs. The advantage of the applied synthetic method is that it provides control over the material morphology, leading to uniform and full cover of the CNFs and CNTs with no individual formations of material away from the carbon. To the best of our knowledge, the deposition of MoS2 on CNFs has not been reported elsewhere.
