From nano-test tube chemistry we determine details of low temperature growth of carbon nanotubes. Single-walled carbon nanotubes of various diameters are grown at different temperatures from a Pt organometallic precursor encapsulated inside template single-walled tubes. At the low temperature limits where the reactions are slower and milder, the inner-tube diameters are optimally determined by the outer-tube diameter. The growth temperature is determined for a given tube chirality and is found to be dependent on the diameter. It is lower for thinner tubes and can be as low as 600 degrees C for the (7.3) tube. In situ nano-test tube chemistry within a state-of-the-art microscope provides an idealistic nano-clean room experiment, which allows monitoring of a snapshot in the catalytic growth of a single-walled tube out of a Pt nanocrystal.
