Abstract:
1. A method of purifying a single-walled carbon nanotube catalytic product, the method comprising: providing a catalytic product comprising single-walled carbon nanotubes and at least one Group VIII or Group VIb transition metal disposed upon a support material; exposing the catalytic product to a heated oxidative gas to provide a treated carbon nanotube product comprising single-walled carbon nanotubes and the at least one Group VIII or Group VIb transition metal and the support material; and exposing the treated carbon nanotube product to HF acid to separate the single-walled carbon nanotubes from the at least one Group VIII or Group VIb transition metal and the support material.
