Multi-walled Carbon Nanotubes (MWCNTs) coupled with TiO2 nanoparticles was successfully synthesized using sol-gel method at room temperature. Titanium isopropoxide and MWCNTs were selected as starting materials. The presence of anatase TiO2 phase in the MWCNTs/TiO2 composites was determined by XRD analysis. In addition, FTIR analysis was conducted to determine the chemical bonding of MWCNTs/TiO2 composites. Interestingly, it was found that the shifting of absorption edges of TiO2 nanoparticles towards to the visible-light region due to the incorporation of MWCNTs using UV-Visible spectroscopy. The photocatalytic activity of MWCNTs/TiO2 nanocomposites was demonstrated by the Rhodamine B degradation.

Abstract In this study, some types of composites consisting of multi-walled carbon nanotubes (MWCNTs) and spinel oxide (Co, Ni)3O4 were synthesized by simple evaporation method. These composites were characterized by UV–Vis diffuse reflectance spectroscopy, X-rays diffraction(XRD), Scanning electron microscopy (SEM) and specific surface area(SBET). The photocatalytic activity of the prepared composites was investigated by the following removal of Bismarck brown G (BBG) dye from its aqueous solutions. The obtained results showed that using MWCNTs in combination with spinel oxide to produced composites (spinel/MWCNTs) which succeeded in increasing the activity of spinel oxide and exhibited higher photocatalytic activity than spinel oxide alone. Also it was found that, multiwalled carbon nanotubes were successful in increasing the adsorption and improving the activity of photocatalytic degradation of Bismarck brown G dye(BBG). The obtained results showed that spinel/MWCNTs was more active in dye removal in comparison with each of spinel oxide and MWCNTs alone under the same reaction conditions. Also band gap energies for the prepared composites showed lower values in comparison with neat spinel. This point represents a promising observation as these composites can be excited using a lower energy radiation sources.
