The photo-catalysts (TiO2) were synthesized by thermal decomposition of titanium isopropoxide, Also Prepared TiO2 and commercialized TiO2 (P-25,Deggussa) were modified respectively using impregnation with H2PtCl6 solution and the mixed solution which leached metals out from wasted catalytic converter of automobile. Modified catalysts were characterized by band gap energy and position, structure, adsorption properties on temperature, and surface area. we were used XRD, EXAFS, XANES, UV-DRS, BET sueface area analyzer, NH3- TPD and HRTEM for their characterization. And they were tested photocatalytic effects by photocatalytic reactor in gas and liquid phase.
