This particular type of surface nanostructuration allows the preparation of CeO2 nanoparticles in which {111} nanofacets contribute significantly to their surface crystallography. This transformation of the surface structure plays a key influence on the behavior of ceria as a support of gold catalysts. Thus, the appearance of well-developed {111}-nanofacets leads to a much higher efficiency in the usage of this noble metal in the synthesis of catalysts when prepared by the deposition−precipitation method. Moreover, gold catalysts supported on the surfacereconstructed oxide present an intrinsic (per gold surface atom) CO oxidation activity much higher than that of catalysts prepared on the nontreated oxideengjournal articlehttps://doi.org/10.1021/acscatal.5b00086restricted access546CeriaGoldSurfacesCatalysisTransmission electron microscopyQuímica inorgánica (Química)2210.01 Catálisis
