摘　　要：An activated foam-structured carbon-ceramic（AFCC） was prepared and investigated as TiO2 support for the photocatalytic degradation of phenol. AFCC and TiO2/AFCC catalysts were characterized by N2 adsorption- desorption and X-ray diffraction（XRD）. The effects of AFCC on the photocatalytic activity and the crystallinity of TiO2 were studied. The results show that the crystallinity and anatase/rutile ratio of TiO2 loaded on AFCC could be significantly influenced by the calcination temperature. The degradation rate of phenol benefited from the synergistic effects of the adsorption of activated carbon（AC） and the photocatalysis of TiO2, which suggests that a high surface area of AC is essential to achieve high degradation rates and efficiencies. It was found that the larger mean cell size of AFCC increased the lizht transmission within the foam.An activated foam-structured carbon-ceramic（AFCC） was prepared and investigated as TiO2 support for the photocatalytic degradation of phenol.
