General description

Potassium hexachloroplatinate (K2PtCl6) is the inorganic compound that is commonly used as a platinum (Pt) precursor for the preparation of platinum-based compounds.

Application

Potassium hexachloroplatinate (K2PtCl6) can be used to synthesize:

  • K2PtCl6-PEG/SiO2 complex catalytic system for vapor-phase hydrosilylation reaction.
  • Pt-decorated nickel pyrophosphate β-Ni2P2O7/Pt and nickel phosphate Ni3(PO4)2/Pt catalysts for the hydrogen evolution reaction (HER) by water splitting.
  • Polypyrrole-platinum complex sphere catalyst for the decomposition of hydrogen peroxide to form oxygen.
For small scale and high throughput uses, product is also available as ChemBeads (932175)
