Enabling the first-principles modelling of electrochemical interfaces at the molecular level

In this talk, I will outline the key challenges in simulating electrified interfaces at the nanoscale and demonstrate how I address them by implementing voltage control in ab initio molecular dynamics [1–3]. Focusing on the Pt(111)–water interface, I will present the first direct, atomic-scale observations of this interface under operating conditions, revealing how the applied potential reorganises the interfacial nanostructure, modulates polarisation mechanisms, and alters chemisorption energies [3–5]. I will then briefly highlight my plan to develop machine-learning force fields that retain near-DFT accuracy while running orders of magnitude faster, and show how my methodologies may be applied to predicting kinetic barriers in electrocatalysis, corrosion, and sensing.
