Synthesis of SnS2 nanocrystals via a solvothermal process

Nanoparticles of tin disulfide have been successfully prepared by the solvent- thermal synthesis method using different precursors. The X-ray powder diffraction patterns showed that the products were hexagonal SnS2 phase and transmission electron microscope images displayed that the samples were laminar particles with the average size of about 150 nm. The Raman spectra showed a sharp peak at 311 cm(-1), which is characteristic of SnS2. The IR spectra determined the absence of tin oxides. In addition, the possible routes of the reactions were discussed. (C) 2001 Published by Elsevier Science B.V.
