TiO2-SiC was prepared by oxidization of TiC-SiC precursor which was obtained by carbothermic reduction process of TiO2-SiO2. XRD analysis indicated the formation of the mixture of anatase and rutile phases of TiO2 crystalline after the oxidation of TiC-SiC sample. TiO2-SiC photocatalyst exhibited the higher photocatalytic reactivity than TiO2 loaded on SiO2 (TiO2-SiO2) prepared by the conventional sol-gel method and commercial TiO2 powder (P-25). These results indicated the advantages of SiC powders as catalyst support of the TiO2 photocatalyst.

TiO2/SiC was prepared by oxidizing the TiC-SiC precursor obtained by carbothermic reduction process of TiO2-SiO2 binary oxide. An XRD analysis indicated the formation of the mixture of anatase and rutile phases of TiO2 crystalline after the oxidation of TiC-SiC sample. TiO2/SiC photocatalyst exhibited a higher photocatalytic reactivity than TiO2-SiO2 binary oxide prepared by the conventional sol-gel method. These results indicate the advantages of SiC nano powders as catalyst support of the TiO2 photocatalysts, and TiO2/SiC photocatalyst is effective for the degradation of organic compounds diluted in water.
