Optimizing catalyst nanop article distribution to produce densely-packed carbon nanotube growth

摘要

The experimental parameters involved in the formation of the Ni catalytic nanoparticles on Si/Si02 substrates that seed carbon nanotube growth were investigated. It was found that after deposition of a nickel film on the substrate, the temperature and time of the thermal and reduction catalyst pre-treatment steps are crucial variables for optimized nanoparticle distribution with different average diameters, depending on the initial film thickness. Densely-packed carbon nanotube forests with interesting potential applications have been grown from this nanoparticle distribution.
