The adsorption of O atom on Cu (100), (110), and (111) low-index and step defect surfaces

Article Abstract:

The five- parameter Morse potential (5-MP for short) of interaction between adatom and metal cluster was constructed, and the adsorption of an O atom on Cu (100), Cu (110), Cu (111), Cu (211), and Cu (410) surfaces was studied by means of 5-MP. Low experimental vibrations were noticed for the O atom on the Cu (111) surface.

Interaction of hydrogen with RuO(sub 2)(110) surfaces: Activity differences between various oxygen species

Article Abstract:

The interaction of hydrogen with RuO(sub 2)(110) surfaces was studied by means of thermal desorption and vibration spectroscopies. It is shown that the RuO(sub 2)(110) surface is highly active in a number of catalytic surface reactions and nicely serves as a model system to study some basis questions in catalysis on oxides.
