General description

Trimethyl(methylcyclopentadienyl)platinum(IV) is a crystalline organometallic precursor for platinum and is used in microelectronics, catalysis, photonics, and chemical sensing processes. It is also utilized as a precursor for preparing platinum nanoparticles, tuning particle size for better activity and stability of the platinum catalyst.

Application

Trimethyl(methylcyclopentadienyl)platinum(IV) can be used:
  • As a precursor to deposit Pt on tungsten oxide surface by atomic layer deposition method. This acts as a hybrid anode catalyst for PEM fuel cells.
  • To fabricate high performance and stable Si photocathode for solar water splitting reaction.
  • As a precursor to deposit Pt nanoparticles on TiO2 nanotube films for highly efficient gas sensors. Pt nanoparticles significantly enhances the sensitivity.
