PbS and Ag2S nanorods have been synthesized using a polyol process in the presence of poly(vinylpyrrolidone) (PVP). First, the production of Pb or Ag was realized via the thermal decomposition of a lead/silver salt. Then the Pb or Ag precursor was directly combined with S power under heating, leading to the formation of the final products. The samples were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). PbS cubes and cubes with a hole in the center were prepared under different reaction conditions. Possible formation mechanisms of different PbS or Ag2S morphologies have briefly been discussed.
在聚乙烯吡咯烷酮（PVP）存在的情况下，采用多元醇法合成了硫化铅（PbS）和硫化银（Ag₂S）纳米棒。首先，通过铅/银盐的热分解实现铅或银的生成。然后，将铅或银前驱体在加热条件下直接与硫粉结合，从而形成最终产物。通过X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和能量色散X射线光谱（EDS）对样品进行了表征。在不同反应条件下制备了中心有孔的硫化铅立方体和立方体。简要讨论了不同硫化铅或硫化银形态可能的形成机制。
