Quantitative Determination of Adsorbate-Adsorbate Interactions
Physical Review Letters, 1999A new concept called configuration distribution analysis is introduced to extract quantitative information on adsorbate-adsorbate interactions from high-resolution scanning tunneling microscopy data. From atom-resolved nitrogen island configurations on an Fe(100) surface we show that the propensity to form small, compact $c(2\ifmmode\times\else ...

AbstractA qualitative interpretation is proposed to interpret isosteric heats of adsorption by considering contributions from three general classes of interaction energy: fluid–fluid heat, fluid–solid heat, and fluid—high‐energy site (HES) heat. Multiple temperature adsorption isotherms are defined for nitrogen, T=(75, 77, 79) K, argon at T=(85, 87, 89)

Abstract CO is adsorbed at 298 K only on the (0001) faces of polycrystaltine αCr 2 0 3 with the appearance of a single i.r. peak whose frequency shifts from 2185 (θ ≈ 0) to 2170 cm -1 (θ max ). This shift is due to the building up of adsorbate-adsorbate interactions (dynamic and static). The dipole--dipole (dynamic) interaction has been measured by

Light-responsive adsorbents with tunable adsorbent–adsorbate interactions for selective CO2 capture
Chinese Journal of Chemical Engineering, 2022Abstract Amines in porous materials have been employed as active species for the selective CO2 adsorption from natural gas because of their target-specific interactions. Nevertheless, it is difficult to modulate such strong interactions to reach a high efficiency in the adsorption processes.

Abstract We investigated the chemisorption of Na and K alkali-metal atoms on the Al(111) surface from very low coverages (Θ = 1 16 ) up to full a monolayer. The calculations predict site and bond-length changes of the adsorbate atoms, as well as a condensation into islands with increasing coverage. Some processes are activated which implies

Localized adsorbate—adsorbent interactions on florisil
Journal of Chromatography A, 1984Abstract Localized adsorbate—adsorbent interactions were investigated by studying equilibrium adsorption of pyridine and n -butylamine on Florisil. The discontinuity of the Langmuir isotherms and heat of adsorption of pyridine were analyzed by the “patch” theory of adsorption on heterogeneous surfaces.

Theory1 of multivalency of adsorbates on metal surfaces, taking into account the effect of the image-force stabilization measured by η2 in addition to those of the electron-transfer between the adsorbate and the substrate measured by Γ and Coulomb interaction between the adsorbate electrons, has revealed that the critical lines exist in a parameter ...
