Growth of WS₂ Nanotubes Phases

Recently, a method to produce bulk quantities of pure multiwall WS 2 nanotubes, which could reach several microns in length, has been developed. A detailed study of the growth mechanism of these WS 2 nanotubes has been undertaken, which is reported hereby. A series of experiments were conducted to define the key parameters, which determine the shape of the WS 2 nanotubes. An alternative approach for the synthesis of WS 2 nanotubes, starting from long WO 3 - x nanowhiskers, which can be extended for the synthesis of other nanotubes, is described as well.
