A 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 کاملSubstrate-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 کاملNature, strength, and consequences of indirect adsorbate interactions on metals
Atoms and molecules adsorbed on metals affect each other indirectly even over considerable distances. Via systematic density-functional calculations, we establish the nature and strength of such interactions, and explain for what adsorbate systems they critically affect important materials properties. This is verified in kinetic Monte Carlo simulations of epitaxial growth, which help rationaliz...
