Interface Chemistry and Structure
At the Interface Chemistry and Structure group, we investigate solid-liquid interfaces, which are fundamental to both natural and technological processes. These interfaces are a critical nexus for energy conversion, catalysis, and environmental remediation. They are where electrons meet molecules, and where the interplay between electrode surfaces, solvent molecules, and ions determines the activity and selectivity of reactions.
Our research combines cutting-edge in situ microscopy with detailed structural analysis to uncover how nanoscale interfacial heterogeneities, in both electrode surfaces and the three-dimensional solvent organization, govern macroscopic performance. Through these insights, we aim to enable knowledge-driven design of next generation catalysts and clean energy technologies.

ncAFM 2026 Conference in Innsbruck
The 27th International conference on non-contact atomic force microscopy (ncAFM 2026) took place in Innsbruck from 3–7 August 2026, bringing together more than 150 researchers from around the world to discuss the latest advances in non-contact atomic force microscopy (nc-AFM) and its applications. The conference was jointly organized by Laerte Patera, Jan Balajka, Martin Setvin and Andrea.
The scientific program covered recent developments in instrumentation, atomic-scale imaging, spectroscopy, and applications in surface and nanoscience, providing a platform for scientific exchange and international collaboration within the nc-AFM community.
Our group also contributed two posters presented by Lucas, “Force Microscopy at the Electrified Solid-Liquid Interface with Tip Apex Modification”, and Fabian, “Probing the In2O3 – water interface with STM and AFM”.

New article published in Electrochimica Acta
The article, “Field-related interfacial effects on structure and surface chemistry during the initial stages of Cu(111) oxidation,” investigates the structural and electrostatic changes occurring during Cu(111) oxidation. By combining laser-induced temperature jump experiments with in situ EC-STM, the study reveals how hydroxide adsorption, oxygen formation, and the transition from two-dimensional to three-dimensional Cu2O growth reshape the surface structure and interfacial electric field. The study was led by Andrea in collaboration with Julia Kunze-Liebhäuser (University of Innsbruck), Victor Climent and Juan Feliu (both University of Alicante).

New visiting student
We are happy to welcome Ariba Adnan from Leiden University as a visiting PhD student in our group for a period of almost four months. During her stay, she will work on in situ AFM, contributing to our research on the structure of the electrical double layer.
We look forward to a productive collaboration and many inspiring discussions.

New article published in ACS Electrochemistry
How does gold oxidize under alkaline conditions? The new article, “Oxide Growth and Place-Exchange on Au(111) in Alkaline Electrolyte,” investigates this process and shows, using in situ EC-STM.

New article published in ACS Nano
A recent study published in ACS Nano, with Andrea Auer as corresponding author and carried out in collaboration with Julia Kunze-Liebhäuser (University of Innsbruck), investigates CO oxidation on Cu single crystals as a model reaction for low-temperature fuel cells.
In-situ surface imaging under reaction conditions reveals facet-dependent restructuring of the Cu surface, showing that catalytic activity is largely governed by the effective density of active Cu adatoms rather than distinct structural motifs.

New article published in Angewandte Chemie
Changes in electrode surface chemistry under electrochemical conditions critically influence electrocatalytic performance. In this communication, in-situ electrochemical X-ray photoelectron spectroscopy was employed to monitor the surface state of tungsten carbide (WC) powder electrodes during the hydrogen evolution reaction (HER) and at oxidative potentials. This study was led by Julia Kunze-Liebhäuser (University of Innsbruck).
