Jobbeschreibung

Postdoc - Correlative In Situ Electron Microscopy and Operando X-ray Study of Catalyst Restructuring and Degradation in LOHC (De)hydrogenation (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 Interfaces for Chemical Hydrogen Storage" (IHE-1), led by Prof. Dr. Hans-Georg Steinrück and Prof. Jungwon Park from SNU.

The goal of this research topic is to understand how the atomic structure of supported metal catalysts evolves at the catalyst–LOHC interface under reaction conditions, and how this evolution governs activity, selectivity, and long-term degradation.

Your Job

• Resolve atomic-scale restructuring, sintering, and leaching of Pt-based nanoparticles and clusters using in situ gas/liquid-phase and identical-location TEM
• Correlate local TEM observations with ensemble-averaged operando high-energy X-ray scattering and spectroscopy under realistic temperature and H₂ pressure
• Identify the interfacial origins of side reactions (C–C bond cleavage, carbonaceous deposits) and their link to catalyst deactivation and carrier degradation
• Establish structure–degradation descriptors as design principles for durable, low-precious-metal 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 isrequired(at least B2 level according to the CEFR)
• 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
