Adsorption and reaction of methanol on stoichiometric and defective SrTiO3(100) surfaces

Article Abstract:

The adsorption and reaction of methanol (CH3OH) on stoichiometric (TiO2-terminated) and reduced SrTiO3-(100) surfaces are investigated using temperature-programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), and first-principles density-functional calculations. Theoretical calculations predict weak adsorption of methanol on TiO2-terminated SrTiO3(100) surfaces.

Adsorbate-induced segregation in the Ni{111}/Au/(R,R)-tartaric acid system

Article Abstract:

The adsorption of the catalytically important chiral modifier, (R,R)-tartaric acid, was investigated on bimetallic Ni/Au surfaces created by annealing thin Au films on Ni{111}. Reflection adsorption infrared spectroscopy measurements revealed that the adsorption mode of (R,R)-tataric acid depends strongly on the surface composition.

Quantitative analysis of adsorbate induced segregation at bimetallic surfaces: improving the accuracy of medium energy ion scattering results

Article Abstract:

Quantitative analysis of adsorbate induced segregation at bimetallic surfaces and the possibility of improving the accuracy of medium ion energy scattering results is presented. It is seen that the segregation processes induced by adsorption are localized to the top few layers of the surface.
