Synthesis of solvent-stabilized colloidal nanoparticles of platinum, rhodium, and ruthenium by microwave-polyol process.

Solvent-stabilized Pt, Rh, and Ru colloidal nanoparticles were synthesized by a microwave-polyol process. They were characterized by TEM and XPS, XRD, and UV-vis examination. These colloids have small particle sizes with narrow size distribution, and they were stable in glycol upon storage under ambient condition for months. Separation and XPS… (More)
