Synthesis, structural and morphological characterization of CeO2-Zn O nanosized powder systems from Pechini's method

This work reports on the investigation of nanosized CeO2-Zn O systems prepared by Pechini's method. The structural and morphological characterization of CeO2-Zn O systems as well as the characterization of CeO2 and Zn O separately, showed that the employed method result in powders with spheroidal particles whose size are in the range 30 - 200 nm, which is appropriate to provide homogeneous suspensions. The Zn O present in the prepared mixed oxides seems to increase particle size distribution and to influence the arrangement of the particles after powder dispersion.(author)
