In this study, monometallic Pt and Pt-Pd, Pt-Ce, Pt-Pd-Ce were supported to TiO2. In order to distribute metals uniformly, hydrogen spillover control was used. Toluene, Xylene and MEK were used reactants. The monometallic and bimetallic catalyst were prepared by the excess wetness impregnation method and characterized by XPS, BET, XRD and TEM analysis. In the VOCs oxidation, Pt and Pd monometallic catalysts had multipoint active sites, so they improved the range of Pt, Pd, Ce metal state. And Pt-Pd, Pt-Ce, Pt-Pd-Ce bimetallic catalysts were high conversion of VOCs. In addition to, HSO controlled catalysts on the TiO2 supporters promoted oxidation conversion of VOCs. |
