Descrizione

Descrizione generale

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.

Applicazioni

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.
