Hydrogen interacts strongly with the undercoordinated O atoms, thereby forming hydroxyl ...

Literature showed that Au nucleates at step edges on oxidized samples. For oxidized samples we found that the Au dispersion is dependent on the surface roughness. A rough CeO2 surface has a higher step density, which results in a Au higher particle density with a smaller average diameter. Other studies showed that Au nucleates on oxygen vacancies on reduced CeOx substrates. We found that small Au particles adsorbed on oxygen vacancies exhibit a significantly higher Au 4f binding energy than Au particles on oxidized CeO2. Relatively less CO adsorbs on small Au particles on a reduced substrate, with a significantly lower adsorption energy than on Au on an oxidized substrate. For larger particles the influence of oxygen vacancies in the substrate is negligible.

The measurements show that a specific thin surface oxide is always present in the high activity regime of Rh-based CO oxidation.
