Multiwalled carbon nanotube (MWCNT) enhanced MWCNT/TiO2nanocomposites were synthesized by surface coating of carbon nanotube with mixed phase of anatase and rutile TiO2through a modified sol-gel approach using tetrabutyl titanate as raw material. The morphological structures and physicochemical properties of the nanocomposites were characterized by FT-IR, XRD, DTA-TG, TEM, and UV-Vis spectra. The results show that TiO2nanoparticles with size of around 15 nm are closely attached on the sidewall of MWCNT. The nanocomposites possess good absorption properties not only in the ultraviolet but also in the visible light region. Under irradiation of ultraviolet lamp, the prepared composites have the highest photodegradation efficiency of 83% within 4 hours towards the degradation of Methyl Orange (MO) aqueous solution. The results indicate that the carbon nanotubes supported TiO2nanocomposites exhibit high photocatalytic activity and stability, showing great potentials in the treatment of wastewater.

Walled Carbon Nanotubes

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.
