一般描述

基材原子序数:74钨
Tungsten hexacarbonyl is an organometallic compound that looks like a white crystalline solid. It is volatile and stable in inert environments. While it doesn′t dissolve well in water, it dissolves easily in non-polar organic solvents. This compound is mainly used in organometallic chemistry and materials science, especially for depositing tungsten films using chemical vapor deposition(CVD).

应用

用于制备含钨络合物或纳米材料的前体。也可用于光化学
通过 6-endo 方式或柯普重排反应,用作硅氧基三烯的光化学环化中的催化剂。
Tungsten hexacarbonyl is used as a
  • Reducing agent in the synthesis of uniform single and binary metal nanoparticles, for applications in catalysis, electronics, and materials science.
  • Shape-directing agent in the low-temperature synthesis of non-spherical nickel nanocrystals, enabling the controlled formation of fivefold twinned nanorods and nanocubes with room-temperature ferromagnetic properties.
  • Precursor in metal-organic chemical vapor deposition to synthesize Rhenium-Tungsten(Re–W) nanoparticles on carbon nanotubes
  • Precursor in the aerosol-assisted chemical vapor deposition of WO₃ thin films, enabling the fabrication of hybrid heterojunction gas sensors with high sensitivity and stability for ammonia detection at room temperature.
  • As an organometallic precursor to create metal-containing nanostructures in electron beam induced deposition (EBID).
  • As a precursor for catalysts in alkene metathesis and ligand substitution reactions. It is commonly used in organometallic synthesis, as one or more CO ligands can be replaced by other donor ligands.

特点和优势

  • 99.99% purity on a trace metals, ensuring optimal performance.
  • Low impurities(≤ 150.0 ppm) in precursors minimize defects in the crystal structure of the synthesized material, enhancing performance and stability and forms uniform WO3 films.
  • Low metal content (such as Na, Zr, Cd, Cu, etc.) leads to reduced site reactions and increased yield in catalytic processes.
