CO adsorption on CeO2 supported Pd8 and Pd8Ox nanoparticles. (a) A linear scaling relationship between the reaction barriers of lattice oxygen vacancy formation and CO and O adsorption energies on Pd8(Ox) and CeO2, respectively. (b) A linear scaling relationship between CO adsorption energies and the charge state of the binding Pd atom. (e,f) Corresponding configurations for CO adsorption on Pd8/CeO2, Pd8/CeO2–x′, Pd8O12/CeO2, and Pd8O6/CeO2 structures, respectively.
