Abstract
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 (scCO(2)) at 40 degrees C and 10.34 MPa. The precursor molecules were then converted to metallic Ru by thermal treatment in flowing N-2 at ambient pressure, resulting in well-dispersed nanoparticles with diameters of approximate to 2 nm.
