Abstract
⺠Oxygen vacancies are extremely important for the properties of ceria. ⺠This is the first theoretical study on the reduction properties of Cu-doped bulk ceria. ⺠We find that the first oxygen vacancy forms almost spontaneously (Evac almost zero). ⺠We find that Cu also affects - facilitates - the formation of a second O vacancy in the material. ⺠In-depth analysis of the relative importance of three different origins of the lowering Evac.
