Abstract

In this work, functionalized multi-walls carbon nanotubes (FMWCNTs) were prepared and mixed with titanium dioxide nanoparticles by sol-gel chemical method using titanium tetrachloride (TiCl4) as a source. A cretin amount of MWCNTs were soaked in a mixture of 0.2ml TiCl4 and 0.1ml HCl forming MWNTs/TiO2 nanocomposite as efficient photocatalytic material. Characterization and measurements on the prepared samples before and after adding TiO2 include x-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and transmission electron microscopy (TEM). The results reveal deposition TiO2NPs on FMWCNTs surface after leaving soaking in mixture of TiCl4 for 24h and that caused to fill the MWCNTs with TiO2 NPs and decorating surface of MWCNTs resulting in formation MWNTs/TiO2 nanocomposites.
