To date, the most common synthetic route for nanotube growth is chemicalvapor deposition (CVD) using a gaseous precursor (e.g., methane, acetylene,etc.) in the presence of a metallic nanoparticulate catalyst. Whilesonochemistry has long been utilized for carbon nanotube (CNT)exfoliation/dispersion and functionalization, there are few reports of thistechnique being used as a synthetic medium for CNT growth. Herein, we explorethe use of a high-energy sonochemical probe to decompose aromatic hydrocarbonprecursors to yield CNTs. Characterization of the resultant products byelectron microscopy, atomic force microscopy, and Raman spectroscopy will bepresented, as well as morphological comparisons to CVD-grown nanotubes.
