Study of the synthesis of self- assembled tin disulfide nanoparticles prepared by a low-cost process

Oleylamine-capped tin disulfide nanoparticles were prepared by the hot-injection method using tin (II) chloride (SnCl2.5H2O) and thioacetamide as tin (II) and sulfur precursors, respectively. The as-prepared nanoparticles were rinsed with ethanol or toluene, and their structural and morphological were assessed by X-ray diffraction, Raman spectroscopy, scanning electron microscopy and transmission electron microscopy. The obtained nanoparticles were single-phase SnS2 with hexagonal structure. These nanoparticles self-assembled to produce spherical 40-50 nm nanostructures after ethanol evaporation, whilst rhombohedral-shaped nanostructures or round-edge nanoribbons were produced after the toluene evaporation.
