摘要
One-dimensional tubular antimony (Sb) nanomaterials were successfully synthesized via a facile template-free solvothermal reduction process. These as-synthesized Sb nanotubes exhibited a middle-hollow, multi-walled, open-ended structures with the average size of lengths and diameters for 370 x 80 nm. Also, they show the rhombohedral phase and good crystallinity in nature. Based on the crystal structures and morphologies evolution of Sb nanomaterials by the temperature-dependent reactions, the formation mechanism of Sb nanotubes has been proposed to be that the nanosized clusters nucleated first and then self-assembly aggregated into thin nanosheets and finally rolled into the nanotubes through some driving forces, namely, a rolling-up mechanism.
