The interaction of O 2 with polycrystalline Co 50 Pd 50 alloy samples was studied by Auger electron spectroscopy (AES) and thermal desorption spectroscopy (TDS). The samples were oxidised in the temperature range of 300-773K with oxygen exposure up to 405L. AES studies revealed surface segregation of Co due to dissociative oxygen chemisorption on the CoPd surface...
The catalytic CO oxidation reaction has been studied on a dysprosium precovered Pt(111) single-crystal surface in UHV (partial pressures of reactants up to 10 -5 Torr range) using mass-spectrometry. The experiments show that the CO oxidation reaction proceeds effectively on the Pt(111) surface in the presence of a submonolayer of coadsorbed Dy (0.05-0.15ML) retaining its bistable behavior...
A non-continuous Rh film was deposited onto the Al 2 O 3 substrate. The sample was annealed and stabilised, and afterwards the CO adsorption/desorption and oxidation/reduction cycles were performed. The gas molecule adsorption was studied by means of thermal desorption spectroscopy and molecular beams. During the experiment, the Auger electron spectroscopy, electron energy loss spectroscopy...
