“…Several synthesis routes have been developed to produced nanocrystalline CeO 2 -based powders. [1][2][3][4][5][6][7] As is well-known, the wet-chemical synthesis methods produce ceramics single or multioxide powders with high sinterability, high surface area, well-defined chemical compositions and homogeneous distribution of the elements. In spite of the quality of the powders produced and although powder synthesis can be achieved at low temperature, many solution processes are complicated and lengthy procedures which limit their applicability.…”
