| 초록 | In this study, monometallic Pt and bimetallic Pt-Ru, Pt-Ir were supported to γ-Al2O3. Xylene, toluene and MEK were used as reactants. The monometallic or bimetallic catalysts were prepared by the excess wetness impregnation method and were characterized by XRD, XPS, TEM and BET analysis. As a result, Pt-Ru, Pt-Ir bimetallic catalysts were showed higher conversion than Pt monometallic catalyst. Pt-Ir bimetallic catalyst was showed highest conversion on the γ-Al2O3 support. In the VOCs oxidation, Pt-Ru, Pt-Ir bimetallic catalyst had multipoint active sites, so it improved the range of Pt metal state. Therefore, bimetallic catalysts were higher conversion of VOCs than monometallic ones. In the kinetics, VOCs oxidation was appeared on the first order reaction. In this study, the use of small amount of Ru, Ir to Pt promoted oxidation conversion of VOCs. |
