Different ratios of composites were synthesis by impregnation methods which consisted of single walled carbon nanotubes with TiO2 (P25). The ratios that used in this works were 0, 0.25, 0.50, and 1.00% from the SWNTs with TiO2. These photocatalysts were characterized by Raman spectroscopy, XRD, UV-visble reflectance, and Surface area (BET) with using total organic carbon TOC to measure the mineralization process for Cobalamin. The result shows that single walled carbon nanotube was succeeding to increase the activity of TiO2 when exhibits higher photocatalytic activity than pristine TiO2. The single walled carbon nanotubes can comparatively better improve the adsorption and activity of photocatalytic degradation of Cobalamin onto TiO2 as compared with pristine TiO2. The results showed that, the adsorption of synthesized composites increases to 4.02% and percent of remaining TOC was 13.79% after 8h, while the synergetic effect R reach to 34% for TiO2/1%SWNTs as compare with pristine TiO2.
