To improve the electrical and catalytic properties of WS₂, the synthesis of WS₂ composites from other materials with good electrical conductivity is a promising approach. Composites are materials in which one material is the matrix and another material is used as the reinforcement. The various materials complement each other in terms of properties and create a synergistic effect, resulting in an overall performance superior to the original material.

Various forms of WS₂ nanomaterials include nanosheets, IF-WS₂, NT-WS₂, and other forms. Chemical gas-solid reactions are the most well-known and established method for the synthesis of IF WS₂ nanoparticles and nanotubes. Tenne et al. initially synthesized IF WS₂ nanoparticles and nanotubes using WO₃ films and H₂S in a reducing atmosphere (95% N₂ + 5% H₂) at 850 °C. However, only a small amount of products could be synthesized by this method.

In WS₂ hybrid structures, atomic doping is one of the effective ways to change the physical and chemical properties of the material, such as band gap and optical properties. For example, Sasaki et al. demonstrated that the exciton absorption peaks at 1.94 and 2.34 eV, respectively, were broadened by Nb doping. This suggests that excitons in WS₂ monolayers are sensitive to Nb doping because of the enhancement of the inhomogeneous broadening rate.

Nanosheets of tungsten disulfide nanomaterials are the most common form, and the main synthetic strategies can be divided into two categories: top-down and bottom-up approaches. Top-down approaches allow the production of small amounts or single-layer samples at a lower cost, which is very beneficial for basic research. Among these top-down methods, mechanical peeling via Scotch tape is the simplest method, with only a few or single layers of WS₂ exfoliated via Scotch tape.
