Hierarchical cobalt sulfide crystals with flower‐like microstructures were successfully prepared by a simple one‐pot solvothermal route, employing CoCl 2 ·6H 2 O as a cobalt precursor and KSCN as a sulfur source. The morphology of these microstructures can be easily controlled by adjusting the molar ratio of glycol to DMF in the solvent. The products were characterized by XRD and SEM. Possible formation mechanisms of CoS hierarchical microspheres are proposed. The influences of the nature of reaction media on the morphological evolution were also investigated and it was found that the ratio of DMF to glycol was of great importance for the formation of CoS morphology.
