Single-walled and multi-walled carbon nanotubes (CNTs) are soluble in toluene containing titanium (IV) tetrabutoxide and their surface could be successfully covered with an ultrathin TiO2 layer. AFM, SEM, TEM, XPS, X-ray and TG-DTA analysis indicate the TiO2 coating on the surface of CNTs through the hydrolysis of bound titanium alkoxid molecules. After calcination at 450-550°C, the SWNTs were completely decomposed from the composites and crystalline TiO2 nanotubes that reflect the shape of the SWNTs were formed. From the XPS results of the prepared TiO2/MWNTs samples, the atomic ratio of Ti to C is circa 1:100, indicating that the coated TiO2 layer is very thin. The current approach provides a new direction for hybridization of CNTs with TiO2 that is photocatalytically active in TiO2/CNTs nanocomposites. [ABSTRACT FROM AUTHOR] |
