Controlled cutting and hydroxyl functionalization of carbon nanotubes through autoclaving and sonication in hydrogen peroxideElectronic supplementary information (ESI) available: Experimental details and DLS results. See DOI: 10.1039/c5cc01115a

In this study, an eco-friendly process utilizing a low concentration of hydrogen peroxide along with autoclaving and sonication was developed, accomplishing both carbon nanotube size reduction and hydroxyl functionalization. An alternative, eco-friendly process utilizing autoclaving and sonication of CNTs in H 2 O 2 was developed, accomplishing hydroxyl functionalization and size reduction.
