In this work, pitch/activated carbon/TiO₂ composite were prepared by CCl4 solvent method with different mixing ratios. The BET surface area of pitch/activated carbon/TiO₂ composite has a significantly increase with increasing activated carbon content in pitch/activated carbon/TiO₂ composite. The surface structure and elemental compositions of the composite were studied by SEM and EDX, respectively. The SEM results were presented to the characterization of porous texture on the pitch/activated carbon/TiO₂ composite. And EDX data was shown the presence of C, O, S, Ti and other elements. The structural properties of the composite were studied in XRD measurements. The TiO₂ crystal phases of the pitch/activated carbon/TiO₂ composite had lots of rutile-type structure which transforms from anatase-type with a little of anatase-type structure. The photocatalytic activities of the composite were evaluated using a photo-decomposition method under UV lamp. The pitch/activated carbon/TiO₂ composites were observed better photocatalytic activity than that of pristine TiO₂.
