Substrate-Adsorbate Coupling in CO-Adsorbed Copper.
The vibrational properties of carbon monoxide adsorbed to the copper (100) surface are explored within density-functional theory. Atoms of the substrate and adsorbate are treated on an equal footing in order to examine the effect of substrate–adsorbate coupling. This coupling is found to have a significant effect on the vibrational modes, particularly the in-plane frustrated translation, which ...
متن کاملA Thermodynamic Investigation of Adsorbate- Adsorbate Interactions of Carbon Dioxide on Nanostructured Carbons
A thermodynamic study of carbon dioxide adsorption on a zeolite-templated carbon (ZTC), a superactivated carbon (MSC-30) and an activated carbon (CNS-201) was carried out at temperatures from 241 to 478 K and pressures up to 5.5 106 Pa. Excess adsorption isotherms were fitted with generalized Langmuir-type equations, allowing the isosteric heats of adsorption and adsorbed-phase heat capacities ...
متن کاملControlling the electronic structure of graphene using surface-adsorbate interactions
Hybridization of atomic orbitals in graphene on Ni(111) opens a large energy gap of ≈2.8 eV between non-hybridized states at the K-point. Here we use alkali metal adsorbate to reduce and even eliminate this energy gap, and also identify a mechanism responsible for decoupling graphene from the Ni substrate without intercalation of atomic species underneath graphene. Using angle-resolved photoemi...
