采用水热法合成了三元卤氧化铋纳米晶带（如Bi24O31Br10、Bi3O4Br、Bi12O17Br2、BiOCl和Bi24O31Cl10）和纳米管（如Bi24O31Br10）。卤氧化铋的组成和形貌可以通过调节一些生长参数来控制，包括反应pH、时间和温度。所有的纳米结构，其特征在于通过使用各种方法，包括X射线衍射，透射电子显微镜，高分辨率TEM，电子衍射和能量色散X射线分析。根据实验结果讨论了可能的反应机理和晶体的生长。
Ternary bismuth oxyhalide crystalline nanobelts (such as Bi24O31Br10, Bi3O4Br, Bi12O17Br2, BiOCl, and Bi24O31Cl10) and nanotubes (such as Bi24O31Br10) have been synthesized by using convenient hydrothermal methods. The composition and morphologies of the bismuth oxyhalides could be controlled by adjusting some growth parameters, including reaction pH, time, and temperature. All the nanostructures were characterized by using various methods including X-ray diffraction, transmission electron microscopy, high-resolution TEM, electron diffraction, and energy-dispersive X-ray analysis. The possible reaction mechanism and growth of the crystals are discussed based on the experimental results.
