چکیده انگلیسی
Interaction of carbon monoxide and oxygen on the surface of titania/Au(1Â 1Â 1) inverse model catalyst held at 200Â K has been studied by reflection absorption infrared spectroscopy. It was found that CO adsorbs on the oxide/Au perimeter interface, whereas no or very weak adsorption was observed on Au(1Â 1Â 1) or titania surface, respectively. Exposing of such species to oxygen results in their decay possibly due to carbon dioxide formation. Efficiency of this effect is higher at lower CO initial concentration which points at the importance of free surface sites for the reaction process.
