C60/TiO2 andV-C60/TiO2composite photocatalysts were prepared with titanium(IV) n-butoxide (TNB) by a sol-gelmethod. Fullerenehad absorptive andsemiconducting properties, and vanadium could enhance the photogenerated electron transfer. The V-C60/TiO2 composite shows a good photo-degradation activity. XRD patterns of the composites showed that the C60/TiO2 composite contained a mixture of anatase and rutile phase forms while the V-C60/TiO2 composite contained a typical single and clear anatase phase. The surface properties seen by SEM and FE-SEM present a characterization of the texture on C60/TiO2 and V-C60/TiO2 composites and showeda homogenous composition in the particles for the titaniumsources used. The EDX spectra for the elemental identification showed the presence of C and Ti with strong V peaks for the V-C60/TiO2 composite. From the photocatalytic results, the excellent activity of the C60/TiO2 and V-C60/TiO2 composites for degradation of methylene blue under UV irradiation could be attributed to both the effects between photocatalysis of the supported TiO2 and charge transfer of the fullerene, and the introduction of vanadium to enhance the photogenerated electrons transfer.
