以Ni（Ac）2·6 H2O和双硫腙为反应物，乙二胺为溶剂，在220 - 240 °C的温度范围内，通过溶剂热法成功制备了高度均匀的海胆状NiS纳米结构。采用X射线衍射（XRD）、场发射扫描电子显微镜（FE-SEM）和高分辨透射电子显微镜（HRTEM）对产物进行了表征。反应温度、硫源和溶剂对最终的海胆状结构有重要影响。在实验结果的基础上，提出了海胆状NiS晶体的可能生长机制，并得到了工艺表征的支持。（© Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2005）
Highly uniform urchin-like nanostructures (in the structures, nanoneedles or nanobelts grow radially from the core particles) of NiS (millerite) were successfully prepared by a solvothermal synthetic route using Ni(Ac)2·6H2O and dithizone as reagents and ethylenediamine as solvent in the temperature range of 220−240 °C. The prepared nickel sulfides with urchin-like 3D architectures were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HRTEM). The reaction temperature, sulfur sources, and solvent are of great importance on the final urchin-like structures. On the basis of the experimental results, a possible growth mechanism of the urchin-like NiS crystals is proposed, which is supported by the technical characterizations.
