Scheme of CO oxidation mechanism and computed potential energy surfaces for CO oxidation. (a) Scheme for CO oxidation without O2 dissociation and (b) scheme for CO oxidation via O2 dissociation at the interface of CeO2 supported Pd nanoparticles. (c,e) Potential energy diagrams for CO oxidation without O2 dissociation. (d,f) Potential energy diagrams for CO oxidation via O2 dissociation on Pd8, CeO2 supported Pd8, and Pd8Ox nanoparticles. The elementary reaction barriers are given in eV.
