Abstract
TOFa based on Pt dispersion varied as a function of dâ0.86 while TOFb based on Pt atoms located on the periphery of Pt-TiO2 interface remained constant at 40 °C, implying that the interfacial Pt atoms could be active sites for CO oxidation. Kinetic results resulted in a rate expression of r = 1.98 x 10â7PCO0.29PO20.19, and elementary steps involving chemisorption of CO on Pt atoms and chemisorption of O2 on TiO2 were proposed.
