Design of Efficient TiO_2/SiC Photocatalysts from TiC-SiC Nano Particles for Degradation of Organic Pollutants Diluted in Water

摘要

TiO_2/SiC was prepared by oxidizing the TiC-SiC precursor obtained by carbothermic reduction process of TiO_2-SiO_2 binary oxide. An XRD analysis indicated the formation of the mixture of anatase and rutile phases of TiO_2 crystalline after the oxidation of TiC-SiC sample. TiO_2/SiC photocatalyst exhibited a higher photocatalytic reactivity than TiO_2-SiO_2 binary oxide prepared by the conventional sol-gel method. These results indicate the advantages of SiC nano powders as catalyst support of the TiO_2 photocatalysts, and TiCVSiC photocatalyst is effective for the degradation of organic compounds diluted in water.
