About this position
This postdoctoral project is part of the SNU/FZJ Energy Fellow Program, a two-year international research collaboration between Forschungszentrum Jülich (FZJ) in Germany and Seoul National University (SNU) in South Korea. The fellow will spend one year employed at FZJ and a second year at SNU, or follow the reverse sequence.
The research focuses on advanced liquid organic hydrogen carrier (LOHC) systems for chemical hydrogen storage. The project aims to clarify dynamic active-site transformations and kinetic degradation mechanisms during LOHC hydrogenation and dehydrogenation. The work combines catalyst synthesis, operando synchrotron X-ray absorption spectroscopy, reactor engineering, multimodal characterization, and artificial intelligence.
At FZJ’s Catalytic Materials for Chemical Hydrogen Storage division (IHE-2), the researcher will develop novel low-precious-metal catalysts and study their performance in LOHC reactions. The project includes designing specialized thermochemical flow reactors for in situ and operando XAS measurements under realistic temperature, pressure, and dynamic fluid conditions.
The fellow will correlate local electronic and atomic structure evolution with macroscopic catalyst performance through operando XAS and ex situ X-ray and electron microscopy. These measurements will be used to identify catalyst deactivation, restructuring pathways, and processes occurring at the catalyst–LOHC interface.
AI-driven data analytics and computer vision will support automated processing of high-throughput synchrotron XAS spectra and experimental microscopy images. The overall objective is to accelerate the discovery of structure–property–activity descriptors for durable LOHC catalysts. The research environment is led by Professor Regina Palkovits at FZJ and Professor Sangwook Park at SNU.
