ABSTRACT: The textural and surface properties of ceria solids prepared in the presence of Triton X reverse micelles and using in situ synthesized Ce(OiPr)4 and Ce(OiPr)3 precursors are compared with one another to investigate the effect of the two different precursors on the ceria particles formation. A wide spectrum of analytical methods such as UV-Vis absorption, isothermal N2 adsorption/desorption, powder XRD, FTIR, ATR-FTIR, DRUV-Vis solid state, TGA and DSC has been employed for the characterization of the solids. Generally, the ceria solids obtained when the Ce(OiPr)4 precursor is used to possess better textural and surface properties, and more defects (e.g. oxygen vacancies) in their crystal structure.
