Urea-stabilized air-stable Pt nanoparticles for thin film deposition

Chem Commun (Camb). 2010 Apr 21;46(15):2683-5. doi: 10.1039/b926736k.

Abstract

The reduction of [Pt(COD)(CH3)2] with CO in the presence of hexadecylamine (HDA) and oleic acid (OlAc) leads to amine carbonylation and formation of an air-stable colloidal solution of N,N'-bis(hexadecyl)urea-stabilized Pt(0) nanoparticles. These air-stable colloidal solutions can be used to form thin films of Pt nanoparticles on a silicon substrate.
