Abstract
High yield catalytic growth of carbon nanotubes (NT's) at extremely low temperatures (<600 K) could be achieved by co-depositing carbon precursors along with Ni(2+) in aqueous solutions using Aerosol-Assisted CVD. Deposition experiments were carried out by using both concurrent decomposition of Ni-based chemicals and Ni colloids. Raman spectroscopy was used to quantify the relative amount of NT's grown over graphite-like carbon. Microscopy was also employed to confirm the deposition of NT's as well to provide further information on the growth mechanism. Modeling of NT nucleation will also be presented, leading to the understanding of the microscopic mechanism of NT embryo formation.
