About TU Darmstadt

TU Darmstadt stands for excellent and relevant science. We are playing a decisive role in shaping far-reaching processes of global change—from energy transition to artificial intelligence—through outstanding scientific knowledge and innovative academic programmes. We group our cutting-edge research into three fields: Energy and Environment, Information and Intelligence, Matter and Materials. We are a university with strong ties to the Frankfurt Rhine-Main metropolitan region and a very strong international focus. We are committed to European values and European integration.

About our working group

The Laboratory for Surface Chemistry and In Situ/Operando Spectroscopy, led by Prof. Christian Hess, is a multidisciplinary research group that works on understanding the mode of operation of catalysts, gas sensors and batteries at the molecular level. Novel spectroscopic approaches are developed and applied to the characterization of materials under working conditions (operando/transient approach). Relationships between (defect) structures and activity/selectivity are studied by combining variety of spectroscopic techniques. Controlled synthesis and nanoscale structuring using atomic layer deposition enable the design of surfaces for applications in catalysis and alternative energy.

The research project

We are currently seeking a Research Assistant (f/m/d) to join our activities in the field of mechanistic investigation of chemical sensors using operando and transient spectroscopy.

Chemical sensors based on metal oxide semiconductors are widely used due to their high sensitivity to target gases and simple production processes. However, the underlying mechanisms (gas sensing, catalysis) remain unclear, hindering the rational design of improved materials. The goal of this project is to elucidate the working principles of technologically relevant metal oxide gas sensors, i.e., materials loaded with noble metals, using state-of-the-art operando and transient spectroscopic techniques. The aim is to develop a comprehensive mechanistic understanding that encompasses the metal oxide, the noble metal, and their interaction.

Your tasks

• Contributing to the above-mentioned research project

• Fabrication and characterization of metal oxide gas sensors (including XRD, XPS, Raman, UV-Vis, SEM/TEM)

• Investigation of the gas sensing behavior in different gas atmospheres

• Establishing structure-property relationships using operando and transient spectroscopy (IR, Raman, UV-Vis)

• Elucidation of the operating mechanisms of metal oxide gas sensors

• Documentation and presentation of research results

• Participation in teaching activities within the field of Physical Chemistry, e.g., supervision of tutorials and lab courses in Physical Chemistry

Your profile

• Completed university degree (M.Sc./Diploma) in Chemistry, Physics, or Materials Science

• Interest in interdisciplinary, experimental research

• Prior knowledge in gas sensing, solid-state chemistry/physics, and/or in situ/operando spectroscopy is advantageous
