Abstract :
Composites of Sn–Pd particles and multi-walled
carbon nanotubes (MWNTs), and of Ni–Co particles
and MWNTs were investigated by transmission electron
microscopy (TEM), energy-dispersive X-ray spectroscopy
(EDS) and X-ray diffraction (XRD). The Sn–Pd particle
composites were prepared by impregnation deposition, and
the Ni–Co particle composites were prepared by electroless
deposition on MWNTs synthesized by a chemical vapor
deposition method using thermal catalytic decomposition
of hydrocarbon. The morphologies and the microstructure
of the deposited particles were investigated upon annealing
the composites with and without hydrogen. Both the
crystalline particle structure and the particle morphology
are observed to be different for the samples annealed with
and without hydrogen.
