Photocatalytic degradation of 2-Propanol diluted in water with TiO 2 photocatalyst deposited on SiC

Abstract

TiO2-SiC was prepared by oxidization of TiC-SiC precursor which was obtained by carbothermic reduction process of TiO2-SiO 2. 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 (TiO 2-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. © 2005 The Surface Science Society of Japan.
