Theoretical analysis of K adsorption on TiO2(110) rutile surface

Article Abstract:

Ab initio Hartree-Fock measurements and molecular dynamics simulations were performed to examine the adsorption of K atoms on a TiO2(110) rutile surface. The interaction was found to be mainly electrostatic. Results also showed that a preferential tri-coordinated K model occurs at low coverages. Moreover, new chemical processes in which the electrostatic forces are less important were observed.

Effect of temperature on surface processes at the Pt(111)-liquid interface: hydrogen adsorption, oxide formation, and CO oxidation

Article Abstract:

Variation of the adsorption pseudocapacitance with temperature can be used to obtain the enthalpy, entropy and free energies of adsorption of Hupd and OHad on Pt(111) as a function of both pH and the form of the anion of the supporting electrolyte.
