KBr here plays two key roles in inducing the growth and self-assembly of Pd@CeO₂ core@shell nanospheres. First, Br^- ions can retard the reduction of Pd²⁺ ions <i>via</i> the formation of the more stable complex of [PdBr₄]^2- so as to tune the size of Pd cores. Second, it greatly decreases the colloidal stability, and hence the surface polarity-weakened Pd and CeO₂ NPs have to spontaneously self-assemble into more stableChemical scienceγ-Al₂O₃ supported Pd@CeO₂ core@shell nanospheres: salting-out assisted growth and self-assembly, and their catalytic performance in CO oxidation.PMC572941391122030, 51272249, 21210001, 21221061, 21401186Li JZhang HWang FWang XLiu DZhen Jfalseγ-Al₂O₃ supported Pd@CeO₂ core@shell nanospheres: salting-out assisted growth and self-assembly, and their catalytic performance in CO oxidation.In this paper, we have successfully demonstrated the clean synthesis of high-quality Pd@CeO₂ core@shell nanospheres with tunable Pd core sizes in water, and furthermore loaded the as-obtained Pd@CeO₂ products on commercial γ-Al₂O₃<i>via</i> electrostatic interaction.
