General description

Trimethyl(methylcyclopentadienyl)platinum(IV) pale yellow or off-white crystalline organometallic complex widely used as a chemical vapor deposition/atomic layer deposition precursor to deposit platinum on various substrates.

Application

Trimethyl(methylcyclopentadienyl)platinum(IV) used:
  • As a precursor to prepare Pt nanoparticles. It helps in tuning the particle size for better activity and stability of the Pt catalyst.
  • To fabricate cathodes for solid acid fuel cells with high activity and excellent stability.
  • To prepare triple helical nanowires(THN) for advanced nanophotonics.
  • To fabricate Pt current collectors for electrodes of asymmetric V2O5–SnO2 nanopore battery.
  • As a precursor for synthesis of Platinum catalystwith high loadings of uniform-sized, 1−2 nm Ptnanoparticles on high surface area Al2O3, TiO2, and SrTiO3 supports. The synthesis ofcatalytic nanoparticles via ALD is a compelling technique for creatinginnovative and useful catalysts.
