Novel precursors were
developed for deposition of Cu and Pd nanoparticles on multiwalled carbon
nanotubes for supercritical carbon dioxide deposition technique.
3-(heptadecafluorooctyl)aniline-vic-dioxime and phenanthrenequinonedioxime were
used as ligands in synthesis of the palladium and copper precursors. All
synthesized ligands and complexes were characterized with elemental analysis, ¹H
and ¹⁹F NMR, FT-IR and magnetic susceptibility technique. Deposition
of these precursors in supercritical carbon dioxide was performed at 363ºK in
the pressure 0.69 MPa H₂ and 27.6 MPa CO₂. Surface
morphology of metal deposited multiwalled carbon nanotubes has been
investigated with X-ray diffraction, high-resolution transmission electron
microscopy and scanning electron microscopy with EDX. TEM micrographs showed
homogenous distributions of Cu and Pd nanoparticles on the multiwalled carbon
nanotubes. The nature and crystallinity of the nanoparticles were confirmed
using XRD. This study showed that these novel vic-dioxime complexes are suitable precursors for the preparation
of supported metal nanoparticles in supercritical carbon dioxide.
