Abstract
Nanotubes of tin disulfide were fabricated from SnS2 nanoflakes by the vapor-liquid-solid process using bismuth nanodroplets as a catalyst. The SnS2 reagent in the gas phase preferentially adsorbs onto the bismuth particles; upon cooling, nucleation and growth of SnS2 nanotubes occurs (see HRTEM image). Annealing the nanotubes results in the formation of SnS 2/SnS superlattices. © 2009 Wiley-VCH Verlag GmbH & Co. KCaA.File in questo prodotto:
