1. A method for synthesis of carbon nanotubes from natural rubber, comprising:
providing a first material including a natural rubber or derivatives thereof;
thermally decomposing the first material at a first temperature into an intermediate material, wherein the first temperature is selected from about 200° C. to about 500° C.;
contacting the intermediate material with a catalyst; and
thermally treating the intermediate material in contact with the catalyst at a second temperature, for forming carbon nanotubes,
wherein the first material comprises less than 10 weight % of vulcanized rubber, or wherein the first material comprises less than 10 weight % of vulcanized rubber and wherein the natural rubber is one or more of latex and coagulated latex.
