应用
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.

备注
Incompatible with strong oxidizing agents and strong acids.

一般描述

The transformation of 2D materials in QDs form supplement excellent properties from their quantum confinement effects, surface-volume ratio, solubility, edge-effects, tunable PL, ease to functionalize and fluorescence properties. These 2D QDs are demanding to impart new dimension to the 2D nanosheets and in order to advance to next level, the better understanding of the properties, synthesis methods and applications of 2D QDs are needed. The exciting optical properties of the WS₂ QDs such as strong excitonic absorption bands covering the visible region, excellent excitonic fluorescence, highly tunable PL, atomically-thin structure, molecular size, biocompatibility, easy functionalization, enhanced photostability, higher molar extinction coefficients and long-term photostability make them attractive candidates for optical sensing.
