Modification of Multi-walled Carbon Nanotubes with Nanoparticles for High Photocatalytic Activity

Titanium dioxide (TiO2) nanoparticles were successfully attached to the outer surface of one dimensional oxidized multi-walled carbon nanotubes (MWCNTs) via sol-gel technique. It was well-established that calcination temperature played a critical role in controlling the crystallinity and phase of MW...
