Synthesis and structural characterization of nanometric ceria highly dispersed in SBA-15 with oxygen exchange capacity
Journal of Materials Chemistry
Nanometric ceria-decorated SBA-15 was prepared using a route involving the impregnation of SBA-15 pores by a solution of cerium(III) 2-ethylhexanoate, followed by its thermal decomposition. According to XRF analysis, the number of successive impregnation-decomposition cycles (IDC) allows control of the CeO 2 /SiO 2 ratio in the final material, and also the tailoring of the nanoparticle size of the fluorite CeO 2 nanoparticles supported in the SBA-15, as confirmed by XRD, Raman and UV-Visdoi:10.1039/c1jm11476j fatcat:nkgwe64xeza27eqh22qkt7tq5u
