PhD Position (F/M/D) – Spatially Resolved Operando Catalysis during CO₂ Activation

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 to join our activities on elucidating the mechanism of CO₂ activation over copper- and gold-based catalysts using spatially resolved catalysis and in situ/operando spectroscopy. The project is closely connected to our ongoing research on CO₂ hydrogenation (RWGS, methanol synthesis).

In light of global warming, the reduction of atmospheric CO₂ is a pressing challenge. Among other measures, the catalytic conversion of CO₂ into value-added products offers a sustainable approach to reducing CO₂ emissions and the dependency on fossil fuels. For the knowledge-driven development of improved catalysts, it is crucial to analyze catalyst structures and, in particular, the nature of active sites under reaction conditions. It is well known that gradients in chemical potential develop inside catalytic reactors, which in turn influence catalyst properties. To achieve a comprehensive understanding of how catalysts operate in CO₂ conversion, the development of spatially resolved methods is essential to identify active species/sites along the catalyst bed.
