Additional Information
Additional comments
At the Institute of Crystallography at RWTH Aachen University, we perform research on highly relevant topics related to the energy transition. We aim for a better understanding of the structure and dynamics of nanostructured solid-gas and solid-liquid interfaces, because of their importance in catalysis, for energy materials and nanomaterials. To achieve these goals, we employ modern X-ray and neutron scattering techniques, both in the laboratory and at large scale research facilities. Our research is placed in the interdisciplinary field of physics, chemistry, geo- and material sciences.
Project description:
The methanation of CO2 using H2 produced via electrolysis of water is an approach for long-term storage of energy from renewable resources. For this purpose, catalysts are needed, that can resist changing gas feed composition. In this project we want to investigate the structure-activity correlation of Ni catalysts on different metal oxide supports such as ZrO2 or CeO2 during catalytic cycling. We will carry out in-situ X-ray scattering experiments with subsequent analysis of the pair distribution function (PDF) to track the nanoparticle size and structure during catalysis and drop-out conditions. In particular, we investigate the effects of oxidative and reducing environments during dropouts onto the catalyst stability and surface restructuring of both support and nanoparticles. For catalytic insight, we use techniques such as infrared and mass spectroscopy, coupled in-situ to the catalytic reactors on a dedicated laboratory diffractometer, and closely collaborate with the group of Prof. Palkovits, RWTH Aachen.
What we offer:
- The opportunity to work flexibly (in terms of location), e.g. in part from home.
- Comprehensive training programs and individual opportunities for personal and professional development.
- Regular work group meetings, travel to beamtimes and conferences.
- Optimal conditions for balancing work and private life, as well as a family-conscious company policy.
- Access to a strong research network at the RWTH Aachen and at FZJ, such as transmission electron microscopy, the JulichSupercomputing Centre, the Neutron-SimLab.
- Public transportation ticket available at a significantly reduced price.
