Postdoc - Thermochemical Operando Synchrotron XAS and AI-Enhanced Reactor Engineering for Advanced LOHC (De)hydrogenation Catalysts (within the SNU/FZJ Energy Fellow Program)

The SNU/FZJ Energy Fellow Program is a prestigious international postdoctoral research program between Seoul National University (SNU) in South Korea and Forschungszentrum Jülich (FZJ). The two-year program offers the opportunity to conduct research at both institutions, starting with a one-year employment at FZJ, followed by a second year at Seoul National University in Seoul under a separate one-year employment at SNU (or vice versa).

This position is joint between FZJ’s institute division "Catalytic Materials for Chemical Hydrogen Storage" (IHE-2), led by Prof. Dr. Regina Palkovits and Prof. Sangwook Park from SNU.

The goal of this research topic is to understand dynamic active-site transformations and kinetic degradation mechanisms in liquid organic hydrogen carrier (LOHC) systems by combining custom operando XAS reactor design, precision catalyst synthesis, and AI-driven data analysis.

Your Job

• LOHC Catalyst Synthesis & System Optimization: Synthesize and characterize novel, low-precious-metal catalysts tailored for efficient LOHC hydrogenation and dehydrogenation processes, leveraging Dr. Regina Palkovits’s pioneering approaches in sustainable chemical hydrogen storage

• Operando XAS Reactor Engineering: Design and construct specialized thermochemical flow reactor systems optimized for synchrotron in situ / in operando XAS measurements under realistic temperature, pressure, and dynamic fluid conditions

• Multimodal Ex/In Situ Characterization: Correlate local electronic and atomic structure evolution (via operando XAS) with macro-scale catalyst performance, using comprehensive ex situ X-ray and electron microscopy techniques to identify deactivation and restructuring pathways at the catalyst–LOHC interface

• AI-Driven Data Analytics & Computer Vision: Integrate AI models for automated processing and feature extraction of high-throughput synchrotron XAS spectra and experimental microscopic images, accelerating the discovery of structure–property–activity descriptors for high-durability LOHC catalysts

Your Profile

• Master's degree with PhD in physics, chemistry, materials science, chemical engineering, or related disciplines

• Experience in energy science

• Very good command of written and spoken English with extensive vocabulary is required (at least B2 level according to the [CEFR](https://go.fzj.de/languagerequirements))

• Very independent and self-motivated way of working but also excellent teamwork skills

• High motivation to take on responsibility and develop your own research ideas

• Willingness for regular business trips
