Synthesis of PVP-stabilized ruthenium colloids with low boiling point alcohols

A route to the preparation of poly(N-vinyl-2-pyrrolidone) (PVP)-stabilized ruthenium colloids by refluxing ruthenium(III) chloride in low boiling point alcohols was developed. Deep purple colloids with shuttle-like ruthenium particles were also synthesized. XPS measurement verified the nanoparticles were in the metallic state. The morphology of metal nanoparticles was characterized by UV–visible absorption spectrophotometry, TEM and XRD.

Dark brown Ru colloids or deep purple colloids with shuttle-like nanostructures can be prepared by refluxing RuCl3 with PVP in low boiling point alcohols.Figure optionsDownload as PowerPoint slide
