摘要：

The oxygen adsorption on CeO2 and Rh/CeO2 has been studied by ESR. Several types of O2- species adsorbed on different sites on cerium oxide and rhodium have been found depending on the treatments. The results indicate that the incorporation of rhodium removes some adsorption sites on CeO2, but generates new ones at the rhodium-cerium oxide interphase, because it favours the formation of oxygen vacancies in CeO2.
