| Popis: | Nanocrystalline tin(IV) sulfide (SnS 2 ) with diverse morphologies were controllably synthesized using organic additives, such as cetyltrimethylammonium bromide (C 16 TAB), sodium dodecyl sulfate (SDS), p -benzenedicarboxylic acid in ethanol solution under mild reaction conditions. By adjusting the type and concentration of the organic additives, different nanostructured SnS 2 were prepared including flower-like, fiber-, layer-rolled and sheet-like forms. Some other factors on the morphology, size and crystallization of the prepared SnS 2 nanostructures were also investigated, including reaction time and temperature. Various techniques were applied to characterize the prepared SnS 2 nanostructures including X-ray diffraction, Transmission Electron Microscopy and UV–Vis spectroscopy. The trace water or hydration water of SnCl 4 ·5H 2 O brings no impurities in ethanol solution despite tin(IV) ions are easy to hydrolyze, and the pure-phase SnS 2 can be synthesized successfully. Thermogravimetric analysis (TGA) shows that the amount of the passivated additive C 16 TAB molecule within SnS 2 is about 6.4 wt.% when the initial molar ratio of C 16 TAB to Sn 4+ is 1:1. This method avoids hydrolyzing and expands the application range of tin salts containing hydration water in synthesizing pure-phase nanocrystalline tin(IV) sulfide. |
