以银纳米线与单质硫为反应物,DMF为反应溶剂,在室温条件下,通过自发的化学反应制备一种具有独特的链状多面体结构的银-硫化银复合纳米复合物。这种多面体链状结构是以银纳米线为核心,多面体硫化银生长在其表面。根据不同反应时间产物的结构特点研究了该结构的生长过程。利用SEM、TEM、XRD对不同反应01时间产物的形貌特征及物相结构进行表征,结果表明,该复合结构具有良好的结晶性和独特的链状多面体结构。
A silver-silver sulfide composite nanocomposite with a unique chain polyhedron structure was prepared by spontaneous chemical reaction at room temperature with silver nanowires and elemental sulfur as reactants and DMF as the reaction solvent. This polyhedral chain structure is based on silver nanowires, polyhedral silver sulfide grows on its surface. According to the structural characteristics of different reaction time products, the growth process of the structure was studied. The morphologies and phase structures of the products with different reaction time were characterized by SEM, TEM and XRD. The results showed that the composite structure has good crystallinity and unique chain polyhedron structure.
