N2 - ABSTRACTMulti-walled carbon nanotubes (MWNT)were produced
by chemical vapor deposition using yttria-stabilized
zirconia/nickel (YSZ/Ni) catalysts. The catalysts were obtained
by a liquid mixture technique that resulted in fine dispersed
nanoparticles of NiO supported in the YSZ matrix.
High quality MWNT having smooth walls, few defects, and
low amounts of by-products such as amorphous carbon were
obtained, even from catalysts with large Ni concentrations
(> 50 wt.%). By adjusting the experimental parameters, such
as flux of the carbon precursor (ethylene) and Ni concentration,
both the MWNT morphology and the process yield could be
controlled. The resulting YSZ/Ni/MWNT composites can be
interesting due to their mixed ionic-electronic transport properties,
which could be useful in electrochemical applications.
