Inorganic fullerene tungsten disulfide nanotube is a new material that has good mechanical properties, electronic transportation properties, together with excellent friction performance. So it has broad application value in many important fields such as electrode materials, hydrogen storage materials, catalysts and so on.

Spherical nano tungsten disulfide can be prepared by hydrothermal method using ionized water as a solvent, sodium tungstate and thiourea, along with hydroxylamine hydrochloride as reducing agent and CTAB as surfactant. It is a simple and cheap preparation method.

Flake tungsten disulfide can be prepared by solid state method. Tungsten powder and sulfur powder (the mass ratio is 1:3) is mixed in vacuum at high temperature in the preparation process. It is a simple, stable and controllable preparation method.

As an efficient preparation method of tungsten disulfide (WS2), high pressure synthesis has attracted more and more attention. The preparation process is simple, low-cost and environmentally friendly. And the prepared tungsten disulfide usually has high density, crystallinity and good symmetry.
