With a few exceptions, most research applying the surface science approach to study ceria based systems has been performed in about the last five years. As evidence for this statement consider that in a 1995 book which presents a comprehesive review of surface science of oxide surfaces only a single reference to cerium oxide surfaces is cited or that in a 1997 review of structural, electronic and chemisorptive properties of metal films and particles on oxide surfaces there are six references to ceria surfaces or that in a 1998 review of surface studies of supported model catalysts there are only six references to ceria as a support. The 

To date the surface science approach and techniques such as those described above have been used to study structure of ceria surfaces, the adsorption and desorption of several molecular species on ceria and model ceria supported catalysts, and the co-adsorption and reaction of certain of these molecular species. The results provide a basis for clarifying the elementary reaction steps underlying catalytic processes occurring on ceria based catalysts. In this Chapter it is attempted to review and summarize this research.
