1. A method of converting waste plastic to carbon nanotubes, comprising:
mixing a carbon-containing material and a metallic catalyst precursor with a solvent to form a mixture, wherein the carbon-containing material is a waste plastic comprising about 0.10 to about 10 weight percent of the mixture;
injecting the mixture into a carrier gas stream and into a heated reaction vessel comprising a plurality of heating zones;
heating the mixture at a first temperature of between about 100° C. and about 1000° C.;
heating the mixture at a second temperature of between about 400° C. and about 1000° C. to facilitate growth of carbon nanotubes; and
removing the carbon nanotubes from the heated reaction vessel.
