In this paper, ZnS one-dimensional (1D) nanostructures including tetrapods, nanorods, nanobelts, and nanoslices were selectively synthesized by using RF thermal plasma in a wall-free way. The feeding rate and the cooling flow rate were the critical experimental parameters for defining the morphology of the final products. The detailed structures of synthesized ZnS nanostructures were studied through transmission electron microscope, X-ray diffraction, and high-resolution transmission electron microscope. A collision-controlled growth mechanism was proposed to explain the growth process that occurred exclusively in the gas current by a flowing way, and the whole process was completed in several seconds. In conclusion, the present synthetic route provides a facile way to synthesize ZnS and other hexagonal-structured 1D nanostructures in a rapid and scalable way.
在本文中，通过无壁射频热等离子体法选择性地合成了包括四足体、纳米棒、纳米带和纳米片在内的一维（1D）硫化锌纳米结构。进料速率和冷却流速是决定最终产物形态的关键实验参数。通过透射电子显微镜、X射线衍射和高分辨率透射电子显微镜研究了合成的硫化锌纳米结构的详细结构。提出了一种碰撞控制生长机制来解释仅在气流中以流动方式发生的生长过程，整个过程在几秒钟内完成。总之，目前的合成路线提供了一种快速且可扩展地合成硫化锌和其他六方结构一维纳米结构的简便方法。
