The Department of Interface Science ( headed by Prof. Beatriz Roldán Cuenya at the Fritz Haber Institute carries out cutting-edge research on advanced functional materials with applications in heterogeneous catalysis, energy conversion and electrochemistry. By combining unique synthesis methods, state-of-the art tools for experimental characterization and advanced approaches to data analysis, atomistic details of thermal catalysis and electrochemical reactions at gas/solid and liquid/solid interfaces are revealed. In particular, structure-reactivity correlations on nanostructured materials can be established, paving the way for the rational design of novel catalytic materials.

We are looking for a PhD or postdoctoral student for the Interfacial Ionics group ( at the Department of Interface Science

PROJECT: Interfacial Water Dissociation and Water Formation

Interfacial water dissociation is important for many electrocatalytic reactions, in particular for producing green hydrogen in alkaline conditions where the concentration of free protons is very low (2 H2O + 2e- H2 + 2OH-). Furthermore, water dissociation can serve as ionic test reaction to study the impact of interfacial water ordering and acid base chemistry on interfacial ionics in general.

The selected candidate will be joining this new research direction that is being established within the ISC department. Your main goal will be to fundamentally improve our understanding of operando water dissociation and water formation during electrocatalysis using novel experimental approaches. Simultaneously, you will also explore new applications.

The PostDoc position is initially for one year but can be extended up to three years.
The PhD candidate is expected to graduate after three years.


We expect candidates to have:
