Abstract—In this paper, synthesis of titania (TiO2) thin film and a nanocomposite of multi-walled carbon nanotubes (MWCNTs) and titania, as MWCNT-TiO2 by sol-gel method, are reported. The samples produced have been studied by XRD diffraction pattern, dispersive micro-raman backscattering spectroscopy and UV-Vis spectroscopy. Results showed that MWCNT/TiO2 nanocomposite has two phases of carbon nanotubes and TiO2 anatase, as expected. The homogeneous sol was prepared by using magnetic stirrer in high rate status and also adding basic material drop by drop. It as observed that the photocatalytic properties of nanocomposite have progressed.

Index Terms—Carbon nanotubes, nano-composite, sol-gel, titania.
