title = "Ion adsorption on metal oxide surfaces to hydrothermal conditions",
abstract = "In this article, we review the sorption of multivalent cations on rutile (α-TiO2) powder surfaces in aqueous 1:1 electrolyte media from room temperature to 250°C. All cations are shown to occupy 'inner sphere' sorption sites in contact with surface oxygens and hydroxyl groups, as well as the diffuse portion of the electrical double layer (EDL). Sorption is shown to increase strongly with increasing temperature, and the sorption affinity is strongly-related to cation radius and charge. Macroscopic powder pH-titration results obtained with ORNL's high temperature hydrogen electrode concentration cells can be rationalized with Gouy-Chapman-Stern models of the EDL, augmented by atomic-scale structural and proton affinity data from synchrotron X-ray studies and computational modeling approaches.",
