To rationalize the anomalously large 𝐶 dl,pzc , Doblhoff-Dier and Koper had to introduce weak (around several hundred meVs) attractive ion-surface interaction, whose origins are unknown currently, to effectively increase the ion concentration in the double layer, shorten the Debye length, and magnify the magnitude of 𝐶 dl,pzc . Recently, Schmickler rationalized the higher 𝐶 dl,pzc as a consequence of weak specific adsorption of anions. Later on, Ojha, Doblhoff-Dier and Koper modified their model by further adopting a two-state submodel for the first-layer water molecules, which was developed earlier by Le et al. It should be noted that a two-state model for water molecules at the IHP was developed first by Watts-Tobin in 1961. The Watts-Tobin model was founded on purely electrostatic considerations, thus the average dipole moment of the water layer is zero at the pzc. As a step forward, the model developed by Le et al. considers chemisorption of water molecules, resulting in a nonzero average dipole moment at the pzc and a C dl peak at a potential higher than the pzc. A three-state model that further considers water-water interactions has been developed by Herein, the target is to develop a double layer model for Pt(111)-aqueous electrolyte interfaces featuring three considerations. First, the present model improves over the two-state water model by the virtue of a statistical treatment of water polarization with a continuum spectrum of orientational states, or an infinite-state water model. In addition to electrostatic interactions, chemical interactions with the metal are considered, as inspired by ab initio molecular dynamics (AIMD) results. Second, the present model abandons the idea of unknown attractive ion-surface interactions that have been introduced to explain the anomalously large '𝐶 dl ' measured by Ojha et al. Instead, it is assumed that 𝐶 dl calculated from CV contains pseudo-capacitance of chemisorption processes. Furthermore, it is assumed that the equilibrium potentials of chemisorption processes follow a distribution instead of take a single value as usual. Third, built upon the second feature, the present model considers chemisorption-induced surface dipole moment as the chemisorbates (adsorbates resulted from chemisorption) are usually partially charged. The present study is a sequel to a previous double layer model considering a two-state water layer and partially charged chemisorbates. That model elucidated that chemisorption-induced dipole moment can change the surface charging behavior from the conventional monotonic mode to a nonmonotonic mode with more than one pzc. It has been shown in that work that polarization of the first-layer water, described using Watts-Tobin's two state model, leads to a negative capacitive component to 𝐶 dl , an effect that was later elucidated in greater detail by Le et al. The present model also amends a few shortcomings of the previous one. Notably, the concept of an oxide layer due to OH adsorption beneath the IHP is abandoned here. Instead, the present model adopts a more realistic picture in which adsorbed OH and first-layer water molecules reside almost in the same IHP.
