ABSTRACT:
Methods of preparing single walled carbon nanotubes from a metal catalyst having deposited thereon fullerenes are provided. Fullerenes are deposited onto a metal catalyst precursor or metal catalyst. In the presence of a carbon containing gas, the metal catalyst precursor/fullerene composition is then exposed to conditions suitable for reducing the metal catalyst precursor, for subliming the fullerene and for growing single walled carbon nanotubes. The fullerenes form the end caps for the resulting single walled carbon nanotubes, which are uniform in diameter.
