The Bi(2)S(3) nanomaterials with various morphologies such as nanorods, nanowires, nanowire bundles, urchin-like microspheres and urchin-like microspheres with cavities have been successfully synthesized through a simple hydrothermal method. Experimental results indicate that sulfur sources play crucial roles in determining the morphologies of Bi(2)S(3) products. Moreover, formation mechanisms of different Bi(2)S(3) nanostructures are discussed based on understanding of the growth habit of Bi(2)S(3) crystal. Finally, we also studied the morphologies-dependent electrochemical and optical properties of the as-synthesized Bi(2)S(3) nanomaterials.
通过简单的水热法成功合成了具有各种形态的 Bi(2)S(3)纳米材料，如纳米棒、纳米线、纳米线束、刺猬状微球和具有空腔的刺猬状微球。实验结果表明，硫源在决定 Bi(2)S(3)产物的形态方面起着至关重要的作用。此外，基于对 Bi(2)S(3)晶体生长习性的理解，讨论了不同 Bi(2)S(3)纳米结构的形成机制。最后，我们还研究了所合成的 Bi(2)S(3)纳米材料的形态依赖性电化学和光学性质。
