Carbon/TiO2 composites were prepared by CCl4 solvent mixing method with different mixing ratios. Since the carbon layers derived from pitch on the TiO2 particles were porous, the Carbon/TiO2 composite series showed a good adsorptivity and photo decomposition activity. The BET surface area for the carbon layer in the sample increases to increasing with pitch contents. The SEM results present to the characterization of porous texture on the Carbon/TiO2 composite and pitch distributions on the surfaces for all the materials used. From XRD data, a weak and broad carbon peak of graphene with pristine anatase peaks were observed in the X-ray diffraction patterns for the Carbon/TiO2. The EDX spectra show the presence of C, O and S with strong Ti peaks. Most of these samples are richer in carbon and major Ti metal than any other elements. Finally, the excellent photocatalytic activity of Carbon/TiO2 with slope relationship between relative concentration (C/C0) of MB and t could be attributed to the homogeneous coated pitch on the external surface by CCl4 solvent method.
