Systematic SM of Pd(111) was performed by O-atom diffusion into the subsurfaces. Virgin and modified Pd(111) catalysts were evaluated for CO oxidation. Typical CO poisoning observed on virgin surfaces was partially lifted, and ambient CO oxidation was observed on the modified surfaces. CO oxidation was followed by the molecular beam method and near-ambient pressure (NAP) photoelectron spectroscopy under different pressure regimes. UV valence band spectral analysis of the SM and the CO+O-2 reaction on modified Pd(111) surfaces under NAP conditions demonstrated changes in the electronic structures of the surfaces with a change in surface potential by 0.35eV and directly probed CO2 formation under the reaction conditions. Supported metal catalysts may be subjected to SM and evaluated for a shift in the catalysis regime for many different reactions.</p>10aheterogeneous catalysis10aOxidation10aphotoelectron spectroscopy10asurface chemistry10asurface modification1 aGopinath, Chinnakonda, S.1 aRoy, Kanak1 aNagarajan, Sankaranarayanan  uhttps://library.ncl.res.in/content/can-we-shift-andor-broaden-catalysis-regime-towards-ambient-temperature-0
