Monitoring oxidation of multiwalled carbon nanotubes by Raman spectroscopy
TL;DR: In this paper, multiwalled carbon nanotubes (MWCNTs) were oxidized in air and acids while varying the treatment time and/or temperature, and it was found that while an oxidation for 6 h in H2SO4/HNO3 provided the strongest effect, a flash oxidation in air (15 min at 550 °C) also leads to an efficient functionalization in a cost-effective and environmentally friendly way.
