Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 3,   Pages 311-320 doi: 10.1007/s11783-010-0237-7

Abstract: Multi-walled carbon nanotubes (MWCNTs)/TiO composite photocatalysts with high photoactivity were preparedCompared to pure TiO, the combination of MWCNTs with titania could cause a significant absorption shiftThe photocatalytic performances of the MWCNTs/TiO composite catalysts were evaluated for the decompositionThe results showed that the addition of MWCNTs enhanced the adsorption and photocatalytic activity ofTiO for the degradation of azo dyes K-6G and MB 7.

Abstract:

Carbon nanotubes/graphene composites have superior mechanical, electrical and electrochemistry propertieswith carbon nanotubes as a hydrophobicity boosting agent.The ever reported synthesis routes towards such a composite either involve complicated multi-step reactions, e.g., chemical vapor depositions, or lead to insufficient extrusion of carbon nanotubes in the chemicalnanotube/reduced graphene oxide composite films.
