According to XRD and TEM results, the addition of citric acid during the impregnation allows obtaining the CeO2 particles with sizes about 3 nm, while the agglomerates of large СеО2 particles are formed on the surface of the SBA-15, when citric acid is not added. Small sizes of ceria particles (3 nm) cause an enhanced reducibility (TPR-H2), high defectiveness of the particles and red shift in the UV-vis adsorption spectra.
