| Abstract: | Hexagonal phase SnS2 nanoflakes have been synthesized by reactions between an organotin precursor tetrabutyltin TBT, (CH2CH2CH2CH3)4Sn] and carbon disulfide in hexanes at 180-200°C for 10-40 h. The structure, morphologies, composition, and properties have been characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED), X-ray photoelectron spectroscopy (XPS), ICP-AES, and Raman and Mössbauer spectroscopies. XRD patterns determined the hexagonal SnS2 with lattice parameters a=3.6384 Å, c=5.9201 Å obtained in n-hexane, and a=3.6389 Å, c=5.9288 Å in cyclohexane. The flakelike morphologies were mainly caused by the anisotropic growth of SnS2. A possible mechanism is given in the paper. |
