Preparation of Y2O3-Doped CeO2 Nanopowders by Microwave-Induced CombusProcess. — The title nanopowders are synthesized in only a few minutes by heat20- 229 tion
ing aqueous solutions of Ce(NO3)3, Y(NO3)3, and urea in a microwave oven. The samples are characterized by TG/DTA, XRD, TEM, and specific surface area measurements. The particle size ranges from 19 to 25 nm, the crystallite size from 14 to 16 nm,
and the specific surface area is about 33—43 m2/g. The nanopowders are important for
solid oxide fuel cells. — (FU*, Y.-P.; LIN, C.-H.; J. Alloys Compd. 389 (2005) 1-2,
