Method for producing carbon nanotubes, method to determine the composition of the catalyst to optimize the production of single wall carbon nanotubes, partu00eccula catalu00ectica metal.Method for optimizing reaction conditions in a method to produce single wall carbon nanotubes, and partu00eccula catalu00ectica to produce carbon nanotubes ".A catalyst and a method for the production of nanotubes by contact of a gas containing carbon with metallic catalytic particles.The catalytic particles contain at least a metal of Group VIII, including, for example, Co, Ni, Ru, Rh, PD, IR, and Pt, and at least a metal from Group VIB, which includes, for example, Mo, W and Cr.The metal component may be deposited on a support. Preferably, a substantial percentage of nanotubes formed are single wall carbon nanotubes.In addition, a method to determine the composition of the catalyst and the reaction conditions for optimization of the production of single wall carbon nanotubes is also exposed.
