Postdoc - Operando X-ray Investigation of Catalyst–Electrolyte Interfaces in CO₂ Electroreduction (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

from SNU. The goal of this research topic is to understand how electrolyte composition and interfacial structure control catalyst reconstruction, reaction pathways, and product selectivity during CO₂ electroreduction.

Your Job

• Resolve dynamic structural changes of Cu-based catalysts under CO₂RR conditions.
• Probe electrolyte-dependent ion and solvent distributions near the catalyst surface.
• Correlate interfacial structure with CO₂RR intermediates and product selectivity.
• Establish design principles for controlling CO₂RR through catalyst-electrolyte interactions.

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

)

• 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
