Abstract (EN): CeO(2), TiO(2) and Ce-Ti-O supports with different Ce/Ti molar ratios were synthesized by solvothermolysis. When titania was combined with ceria, a nanostructured architecture was produced, evidencing the strong influence of Ti on the support structure, so that the Ce-Ti-O supports obtained were mainly amorphous, with some crystalline nuclei. Addition of Ce to titania strongly increases the surface area and oxygen content of samples. Au was loaded on the supports by a double impregnation method. The obtained Au/CeO(2), Au/TiO(2) and Au/Ce-Ti-O materials were also tested for CO oxidation. The differences between samples can be explained by the Au nanoparticle size, which has been proved to be a crucial factor in the preparation of Au catalysts.
