Description

General description

Platinum(II) acetylacetonate is high-purity compound that is widely used as a key precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) methods, to facilitate the synthesis of platinum thin films. These films are utilized in microelectronics, sensors, and catalytic coatings due to platinum′s high thermal stability, chemical inertness, and catalytic activity. Additionally, Pt(acac)₂ is used to synthesize platinum nanoparticles, essential for applications in catalysis and fuel cells.
