Preparation and Morphology Control of Rod-like Nanocrystalline Tin Sulfides via a Simple Ethanol Thermal Route

Rod-like nanocrystalline tin sulfides with different compositions and phases were obtained via simple ethanol thermal reactions between tin chlorides and thioacetamide at relatively low temperature (100°C for 10 h). It is found that solvents, reaction temperatures, and trace water in the system were important factors in obtaining one-dimensional nanocrystalline tin sulfides. The reaction mechanism has also been investigated.
