We have proposed in 1992 that nanoparticles of layered compounds will be unstable against folding and close into fullerene-like structures and nanotubes (IF). Initially this hypothesis was realized in WS_2, MoS_2 and the respective diselenides. Subsequently, nanotubes and fullerene-like structures were prepared from numerous compounds with layered and recently also non-layered structure by various groups. Much progress has been achieved in the synthesis of inorganic nanotubes and fullerene-like nanoparticles of WS_2 and MoS_2 and many other metal dichalcogenides over the last few years.ynthetic methods for the production of multiwall WS_2 nanotubes by sulfidizing WO_3 nanoparticles have been described and further progress is underway. A fluidized-bed reactor for the synthesis of up to half a kg/day of fullerene-like WS_2 nanoparticles has been established in our lab, and the scaling-up of the synthesis to 100 kg/day is under way. The detailed mechanisms for the synthesis of fullerene-like WS_2 and MoS_2 nanoparticles and nanotubes of these compounds have been elucidated.
