General description

Tungsten(VI) chloride is a highly reactive crystalline solid commonly used in the field of catalysis, perovskite solar cells, and light-emitting devices. It is a diamagnetic solid. However, it can be highly corrosive and have strong oxidizing effects.

Application

Tungsten(VI) chloride can be used:
  • As a starting material to synthesize tungsten nanoparticles and Mo-doped urchin-like W18O49 Nanostructure using the hydrothermal method. The Mo-W18O49 electrocatalyst exhibited excellent electrocatalytic activity toward Hydrogen Evolution Reaction (HER). By doping Mo species into defect-rich W18O49 ultrathin nanowires, it has also been demonstrated to be an excellent candidate for photocatalytic N2 fixation to ammonia.
  • To synthesize crystalline mesoporous WO3 with 11 nm pore size utilizing a high-molecular-weight amphiphilic block copolymer as the structure-directing agent. The materials performed admirably in terms of H2S gas sensing.
  • To fabricate Tungsten disulfide and WS2/reduced graphene oxide (WS2/rGO) nanosheets by hydrothermal synthesis. The WS2/rGO nanosheets showed exceptional electrocatalytic activity for the hydrogen evolution reaction.
  • To produce the WS2-nanoflowers@rGO and nitrogen-doped carbon spheres@WS2 composite as an anode material for enhanced electrode performance in lithium-ion batteries.
  • As a dopant to fabricate TiO2 compact layers for perovskite solar cells with enhanced performance.
  • As a catalyst to prepare self-healing epoxy composites with microcapsules.
  • As a catalyst for transamidation of tertiary alkyl amides.
