Constructing High-Dimensional Neural Network Potentials for Oxide-Water Interfaces — •Jan Elsner and Jörg Behler — Theoretische Chemie II, Ruhr-Universität Bochum, Germany, and Research Center Chemical Sciences and Sustainability, Research Alliance Ruhr, Germany

Oxide-water interfaces are promising systems for catalytic water splitting, a process of significant interest due to its potential in sustainable hydrogen production. However, the complex nature of such interfaces and long time scales associated with dynamical processes presents a substantial theoretical challenge. High-Dimensional Neural Network Potentials (HDNNPs) provide a solution to these challenges by enabling atomistic simulations with DFT-level accuracy at only a fraction of the computational expense. We present the construction of a HDNNP suitable for studying oxide-water interfaces with the overarching goal to utilize these HDNNPs for atomistic simulations of these interfaces.
