Abstract
The interaction of hydrous cerium oxide with cationic surfactants unde r basic conditions is used for the first time in the preparation of Ce O2 with enhanced textural and redox properties. The reduction of Ce4to Ce3+ is strongly augmented, especially in the low-temperature regim e, resulting in a broadening of the window of stability of Ce3+. This is accompanied by an increase of thermal stability in the region 900-1 150 K.
