Synthesis of Fullerene- and Nanotube-Like SnS₂ Nanoparticles and Sn/S/Carbon Nanocomposites

SnS 2 nested fullerene-type (IF) nanoparticles, nanotubes, and SnS 2 /C hybrid nanostructures were obtained by vapor transport starting from elemental tin and CS 2 . The reaction was carried out in a single-step process by heating elemental tin metal powder in a horizontal tube furnace at 800−1000 °C. TEM analysis allowed proposing a plausible mechanism for the formation of fullerene-like particles of SnS 2 as well as tubes and scrolls from nanosheets of SnS 2 . Pure material could be obtained by optimizing the reaction based on a product analysis using powder X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) combined with energy-dispersive X-ray spectroscopy (EDX).
