Abstract

This project aims to use a synthesis strategy to prepare zirconi-ceria materials (ZrO2-x%CeO2) to obtains liquid crystalline structures with cubic or hexagonal symmetry. In these synthesis different P123 concentrations (0,5 g; 0,75 g e 1,0 g) will be tested, according with previous works. Also it is planned the expansion of the size of the pores, using a polymeric template plus an oil, aiming to preserve the ordered porous matrix after calcination. Moreover, it is planned to form nano or polycristalline walls, of a cubic or tetragonal single phase, materials that can be used for catalysis and SOFC applications.
