Abstract 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 ·6H 2 O 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.
