Standard adsorption Gibbs energy for hydrogen, OH, chloride, and sulfate on Pt(111): comparison of different isotherms
Standard adsorption Gibbs energy for hydrogen, OH, chloride, and sulfate on Pt(111): comparison of different isotherms
Reliable values of the standard Gibbs energies of adsorption of hydrogen, OH, chloride, and sulfate on Pt(111) are obtained here by means of the application of two suitable isotherms: the “square-root” isotherm and the generalized isotherm. For these calculations, values of surface pressures of adsorbed hydrogen and OH have been obtained from the combination of total and free charge densities; values of coverages have been obtained from the thermodynamic surface concentrations, which are determined from the effect of the concentration of the adsorbing species on the total charge density. The suitability of both isotherms is demonstrated by referring the thermodynamic results to the same standard state

Abstract
Reliable values of the standard Gibbs energies of adsorption of hydrogen, OH, chloride, and sulfate on Pt(111) are obtained here by means of the application of two suitable isotherms: the “square-root” isotherm and the generalized isotherm. For these calculations, values of surface pressures of adsorbed hydrogen and OH have been obtained from the combination of total and free charge densities; values of coverages have been obtained from the thermodynamic surface concentrations, which are determined from the effect of the concentration of the adsorbing species on the total charge density. The suitability of both isotherms is demonstrated by referring the thermodynamic results to the same standard state
