In the present work we present a self-consistent approach to handle the electrode potential in electrochemical interfaces, based on the bond-order dependent ReaxFF force field molecular dynamics approach. This method was applied to describe the electrochemical interface between a Pt(111) electrode and different aqueous electrolytes, with a particular focus on the structure and properties of the predominant water within the interface region as function of the electrode potential. Here, the potential within the double layer region (E < 0. then compensated by counterions to account for charge neutrality of the double layer. This is visualized exemplary in Fig. for a simulated potential of 0.25 V. Here, however, needs to be noted that some simulation cells are not charge neutral, as the number of ions does not equal the charge on the platinum slab. This arises due to the fitting of the number of ions to compensate the free charge density σ Pt 1L rather than the charge within the platinum slab. Altogether, the most realistic courses of the double layer charge were obtained with the systems defined in table , besides, ReaxFF is capable of handling charged systems without limitations.
