•PDMS-Ru nanoparticle composites were prepared using supercritical deposition.•PDMS-Ru nanoparticle composites were prepared without using an immobilization agent.•PDMS films were impregnated with Ru(cod)(tmhd)2 in supercritical CO2.•The impregnated Ru(cod)(tmhd)2 was then reduced to metallic Ru in flowing N2.•The resulting Ru nanoparticles were well-dispersed and had diameters of ≈2 nm.
Nanomaterials consisting of Ru nanoparticles dispersed in polydimethylsiloxane films were synthesized by supercritical deposition. The films were impregnated with the organometallic precursor bis(2,2,6,6-tetramethyl-3,5-heptanedionato) (1,5-cyclooctadiene) ruthenium (II) under thermodynamic control in the presence of supercritical carbon dioxide (scCO2) at 40 °C and 10.34 MPa. The precursor molecules were then converted to metallic Ru by thermal treatment in flowing N2 at ambient pressure, resulting in well-dispersed nanoparticles with diameters of ≈2 nm.
