Abstract
The object of the invention is a process for the synthesis of nanotubes of transition metal dichalcogenides, of fullerene-like nanostructures of transition metal dichalcogenides, of nanotubes of transition metal dichalcogenides, filled with fullerene-like nanostructures of transition metal dichalcogenides, of quasi one-dimensional structures (nanowires, microwires and ribbons) of transition metal oxides and of quasi one-dimensional structures of transition metal dichalcogenides, consisting of fine crystallites of transition metal dichalcogenides. The process is characterized in that the synthesis occurs by the chemical transformation of quasi one-dimensional compounds with a sub-micron diameter, described by the formula M6CyHz, 8.2<y+z≦10, where M is a transition metal (Mo, W, Ta, Nb), C is a chalcogen (S, Se, Te), H is a halogen (I).
