Description

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)
