dc.description.abstract | Nanostructured, doped Ce–Ti mixed oxides are potential materials for several applications such as pigments, catalysis, fuel cells, optical films, and gas sensors. In this article, a series of Pr-doped Ce–Ti oxides have been prepared by the solvothermal method. These compounds were characterized by XRD, Raman, N2 sorption, SEM and UV–VIS spectrophotometry techniques. The experimental results suggest that spherical morphology, nanocrystalline particles and high specific surface area (up to 180 m2 g-1) are achieved at low temperature with this free surfactant methodology. Under basic conditions, a single phase product is identified at high temperature (1000 ºC), while for acid or neutral conditions, secondary phases appear. Different colored materials, ranging from yellow to red, are obtained by varying the firing temperature, quantity of doping praseodymium and the pH of the reaction. The chemical stability of these oxides was tested in some industrial polymers or glazes. | ca_CA |
