1. A method for producing single wall carbon nanotubes comprising the steps of:

  • (a) providing a CO gas stream comprising CO, wherein said CO gas stream is at a pressure greater than about 10 atmospheres;

    (b) providing a gaseous catalyst precursor stream comprising a catalyst precursor;

    (c) mixing the CO gas stream and the gaseous catalyst precursor stream to form a reaction mixture, wherein said mixing step occurs under reaction conditions to form single wall carbon nanotubes; and

    (d) reacting said reaction mixture to form single wall carbon nanotubes.
