Surface chemistry on bimetallic alloy surfaces: Adsorption of anions and oxidation of CO on Pt3Sn(111)

In the present paper, we attempt to provide the insight into the macroscopic level descriptions of the Pt3Sn(111) surface in the electrochem. environment by a combination of ex-situ LEED (LEED), Auger electron spectroscopy (AES) and low energy ion scattering (LEIS) and in-situ surface X-ray scattering (SXS) and Fourier transform IR (FTIR) spectroscopy. In ultra high vacuum (UHV) the clean-annealed surface produces a p(2 x 2) LEED pattern consistent with the surface compn., detd. by LEIS, of 25 at     «
