Abstract

The influence of oxidation and reduction reactions on the surface structure of TiO x thin film which could be produced on Pt(100) was investigated. The changes that occur in this film during subsequent oxidation and reduction reactions were also characterized. It was observed that three dimensional clusters of TiO 2 were produced by the oxidation and annealing procedures. It was found that titanium oxide films on Pt(100) block adsorption of CO at Pt sites at temperatures above 210 K and also these surfaces do not oxidize CO.
