Nanotubes of tin disulfide were fabricated from SnS 2 nanoflakes by the vapor–liquid–solid process using bismuth nanodroplets as a catalyst. The SnS 2 reagent in the gas phase preferentially adsorbs onto the bismuth particles; upon cooling, nucleation and growth of SnS 2 nanotubes occurs (see HRTEM image). Annealing the nanotubes results in the formation of SnS 2 /SnS superlattices.
