Claim 16:
17. A method of converting waste plastic to carbon nanotubes, comprising:
mixing waste plastic and ferrocene with a solvent to form a mixture, the 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 reaction vessel, the reaction vessel including a quartz tube comprising a first heating zone and a second heating zone;
heating the mixture at a first temperature of between about 100° C. and about 1000° C. in the first heating zone;
heating the mixture at a second temperature of between about 400° C. and about 1000° C. in the second heating zone to facilitate growth of carbon nanotubes; and
removing the carbon nanotubes from the reaction vessel.
