  bibo_abstract:
  - A two-step seeded-growth method was refined to synthesize Au@Pd core@shell nanoparticles
    with thin Pd shells, which were then deposited onto alumina to obtain a supported
    Au@Pd/Al2O3 catalyst active for prototypical CO oxidation. By the strict control
    of temperature and Pd/Au molar ratio and the use of l-ascorbic acid for making
    both Au cores and Pd shells, a 1.5 nm Pd layer is formed around the Au core, as
    evidenced by transmission electron microscopy and energy-dispersive spectroscopy.
    The core@shell structure and the Pd shell remain intact upon deposition onto alumina
    and after being used for CO oxidation, as revealed by additional X-ray diffraction
    and X-ray photoemission spectroscopy before and after the reaction. The Pd shell
    surface was characterized with in situ infrared (IR) spectroscopy using CO as
    a chemical probe during CO adsorption–desorption. The IR bands for CO ad-species
    on the Pd shell suggest that the shell exposes mostly low-index surfaces, likely
    Pd(111) as the majority facet. Generally, the IR bands are blue-shifted as compared
    to conventional Pd/alumina catalysts, which may be due to the different support
    materials for Pd, Au versus Al2O3, and/or less strain of the Pd shell. Frequencies
    obtained from density functional calculations suggest the latter to be significant.
    Further, the catalytic CO oxidation ignition-extinction processes were followed
    by in situ IR, which shows the common CO poisoning and kinetic behavior associated
    with competitive adsorption of CO and O2 that is typically observed for noble
    metal catalysts.@eng
