ABSTRACT:
Single walled carbon nanotubes are selectively produced to the substantial exclusion of multi-walled carbon nanotubes by subjecting a mixture of solid hydrocarbon, such as coal, and a transition metal catalyst, to heat generated by an RF induction system sufficient to vaporize both the solid hydrocarbon and the catalyst, and thereafter collecting the single walled carbon nanotubes thereby formed.
