| Abstract: | The oxidation of CO over Pt/Al2O3 has been studied using combined FTIR andin situ reaction cell. During reaction the stretching frequency of the adsorbed carbonyl species remained constant over a temperature range during which a change in the CO conversion occurred. The range of conversion during which this invariance was observed was considerably greater for used catalyst than for fresh Pt/Al2O3. The formation of islands of CO and the role of these in the overall reaction mechanism is discussed. |
