RBS/EBS/PIXE measurement of single-walled carbon nanotube modification by nitric acid purification treatment
Abstract
Single-walled carbon nanotubes (SWCNTs) have many potential applications, including a number of promising biological applications. Nitric acid treatment solubilises CNTs by introducing functional groups, as well as removing amorphous carbon contaminants. Here, we report simultaneous RBS/EBS/PIXE measurements of nitric acid treated SWCNTs, focussing on the metal, nitrogen and oxygen content. We found that nitrogen remains constant in the samples despite washing and dialysis indicating it has either bound irreversibly via intercalation with the SWCNT and/or has been included in functional groups. We also found that the ratio between oxygen and platinum (catalyst) remains constant with treatment time (sampled at 2, 4, 6 h), indicating no more functional groups are made after 2 h exposure.
