Abstract
The research was to perform the characterization and catalytic oxidation of
hydrophobic-supported Pt catalysts which
were prepared in the last project. Highly Pt dispersed catalysts were prepared by incipient wetness method using polymer
(SDB) and activated carbon as supports. Oxidation was carried out by the deep oxidation of benzene and toluene in air. The
chemical status of Pt was revealed by XPS
(X-ray induced photoelectron spectrum). A
redox mechanism was proposed and the
kinetic constants were calculated based on
Mars-van Krevelen mechanism. The results indicated that moistures from atmosphere and oxidation would not be condensed on the
pores/ surface due to hydrophobic surface.
Thus the activity of catalyst was enhanced.
The oxidation of benzene and toluene could be at lower temperatures.
