A novel, cost effective, sonochemical-hydrothermal technique was used for the deposition of nanosized anatase titanium dioxide (TiO 2 ) onto single wall carbon nanotubes (SWCNTs). This technique is described and the characterization of the synthesized TiO 2 -SWCNTs is reported. The characterization techniques employed include scanning electron microscopy (SEM), Raman spectroscopy, and X-ray diffraction (XRD). From the characterization the size and morphology of the synthesized TiO 2 nanoparticles (deposited on the SWCNTs) are reported. Furthermore, it is demonstrated that the created TiO 2 nanoparticles are chemically attached to the SWCNTs. Also, an important correlation between calculated TiO 2 crystal size and the red shifts in the lowest Raman TiO 2 (E. g. ) predominate peak is reported. The synthesized TiO 2 -SWCNTs have potential for large scale production and application in a variety of new technologies such as clean energy power generation devices, electrical storage devices, photocatalysts, and sensors.
