“…1 shows, schematically, the fluorite structure of ceria. The high level of interest is due to important industrial applications such as solid oxide fuel cells, insulators, high refractive index materials, UV blockers, polishing materials, gas sensors, high-temperatureoxidation resistance, free-radical scavengers…etc (see for example [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]). However, the most important applications of cerium oxide are as catalysts, catalyst promoters or catalyst supports, such as those used in automobile mufflers (three-way catalysts) and those related to toxic emission control (e.g.…”
