Although theoretical approaches are attractive in providing structural information and insights into dynamic processes of electrified interfaces on an atomistic level and are able to complement experiments, several challenges still need to be tackled. Different strategies have been developed to include the electrode potential into simulations, such as the widely employed computational standard hydrogen electrode scheme, 14 having the metal electrode exchange electrons with a reservoir, constant Fermi level molecular dynamics, the electronegativity offset method, by introducing fixed excess charges 10, or homogeneous background charges. Also, the description of the aqueous electrolyte differs: From treating the solvent implicitly as a dielectric medium, over explicit but static solvent molecules localized at the electrode to a completely explicit modeling of the electrolyte. Though the explicit modeling is favored in terms of polarization, solvation and accuracy the higher computational cost needs to be considered (e.g. limiting the number of solvent molecules in AIMD simulations to around 100). Here, force field methods can complement first princi-ples calculations by covering significantly larger time and length scales while still providing atomistic, mechanistic and dynamic information. Already, the early conception of a frozen bilayer structure of the interfacial water on certain transition metal surfaces has been modified by including a certain degree of disorder, stressing the importance of including the water dynamics. Furthermore, though adsorbates affect properties of the solvation layer they have not been included in the interface system of most AIMD simulations, with exceptions of selected studies considering adsorbed hydrogen or hydroxide. Adsorbates are, however, especially of interest when simulating the platinum|water interface: More detailed insights into surface coverage effects on the interfacial structure of the adsorbed water layer are highly necessary, taking into consideration the electrode being covered with oxygenated intermediates at electrode potentials relevant for catalytic reactions (e.g. oxygen reduction reaction). Motivated by these questions, in the present work we performed extensive ReaxFF reactive molecular dynamics (MD) studies of the Pt(111)|water interface under the influence of a simulated electrode potential as a function of surface charge densities and surface coverages of oxygenated intermediates. In contrast to various previous studies, we provide a fully self-consistent description of the entire electrochemical interface that includes the surface as well as an extended part of the electrolyte region. We present a detailed analysis of the variation of interfacial water orientation with the applied potential. Our calculations demonstrate the preference of the H-down orientation, with one O-H bond directed towards the surface, in surface oxidation potential region. We further elucidate the thermodynamics of the Pt(111)|water interface by evaluating the course of the entropy from the bulk water to the adsorbed water layer. Our work highlights the importance of complementing the molecular-level picture of the potential-dependent structure and dynamics of the EDL.
