AB - As-synthesised single-walled carbon nanotubes (SWCNTs) are often contaminated withamorphous carbon and residual catalyst particles. These contaminants have a detrimental effecton the effective mechanical and electronic properties, limiting their performance in manyapplications. A comparative series of SWCNT purifications including acid treatments, gasphase purifications and recently-developed reductive purifications have been conducted usinga single commercial SWCNT type (Tuball™). Each of the purification procedures was selectedfor its potential scalability to bulk quantities and evaluated for the extent of impurity removal,SWCNT damage, and overall yield. Raman spectra confirmed that reductive purification usingsodium naphthalide gave the lowest D/G ratio, suggesting that the sp2carbon framework wasmost effectively preserved, while removing a large percentage of the metal impurities.Conversely, nitric acid treatment was most effective at removing catalytic impurities, but thesp2carbon framework was most heavily damaged in the process. The development of scalable,one pot, reductive separations provides a useful new approach to SWCNT purification.
