説明Few-layertungsten disulfide (WS2) film has a 2D-layered structure with a narrow indirect bandgap of of 1.35 eV. In contrast, the monolayer film possesses a direct bandgap of 2.1 eV.
使用Tungsten sulfide is used as a component of catalysts for hydrotreating of crude oil, hydrodesulfurization and hydrodenitrification reactions. It finds application as solid-state secondary lithium battery cathodes and other electrochemical devices. It is found that it forms inorganic nanotubes, which is better reinforcing agents than carbon nanotubes. Tungsten sulfide addition to epoxy resin improves adhesion, fracture toughness and strain energy release rate.
