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.
Application
Platinum(II) acetylacetonate (Pt(acac)₂) is used as a precursor in the synthesis of:
- Pt−Co octahedral nanocrystals, which are used to improve catalytic activity and durability in the oxygen reduction reaction (ORR) in fuel cells.
- PtW@WO3 NPs via thermal decomposition method, serving as efficient catalysts for the hydrogen evolution reaction (HER).
- Monodisperse Pt–Fe nanoparticles, which exhibit high durability for proton exchange membrane fuel cells and provide active and durable low-Pt electrocatalysts for electrochemical devices.
