Abstract

Os and Os-Pd nanoparticles supported on multi-walled carbon nanotubes were prepared by vacuum pyrolysis at 573 K using the [Os3CO10(NCMe)2] and [Pd(acac)2] as precursors. The nanoparticles prepared showed a narrow size distribution (Os: 1.8 nm; Os-Pd: 4.3 nm) and were decorated evenly on the surface of the nanotubes. By controlling the metal-to-nanotube ratio, Os nanotubes were prepared using the carbon nanotubes as a template. The catalysis of Os-Pd nanoparticles towards CVD carbon nanotube synthesis was studied.
