The textural and surface properties of ceria solids prepared in the presence of Triton X reverse micelles and using in situ synthesized Ce(O i Pr) 4 and Ce(O i Pr) 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 N 2 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(O i Pr) 4 precursor is used to possess better textural and surface properties, and more defects (e.g. oxygen vacancies) in their crystal structure.
