Research Groups

Electrochemistry
Group Leader: Prof. Dr.  Beatriz Roldan Cuenya
Our goal is to identify activity, selectivity and stability-determining properties of electrocatalysts and to achieve a comprehensive understanding of the solid-liquid interface under stationary and dynamic electrochemical reaction conditions. We study a variety of catalyst systems ranging from well-defined single crystal surfaces, to thin films, supported size and shape-controlled nanoparticles and industrially-relevant nanocrystalline powder catalysts. more
Liquid Phase Electron Microscopy
Group Leader: Dr. See Wee Chee
Our research aims to derive critical structure-property relationships that control the performance of nanoscale electrocatalysts through in situ characterization with electron microscopy and its associated spectroscopic techniques. In particular, we are interested in operando studies where the imaging of catalysts in liquid environments is coupled with concurrent measurements of their reaction kinetics. more
Operando Hard X-ray Spectroscopy
Group Leader: Dr, Janis Timoshenko
Synchrotron radiation facilities are powerful X-ray sources that can be employed for numerous experimental techniques, including X-ray spectroscopic, scattering and imaging methods. The features of synchrotron radiation - high intensity and broad energy spectrum - make these sources ideally suited for in situ and operando investigations of advanced materials. more
Photo-Electrochemical Scanning Probe Microscopy
Helmholtz Young Investigator Research Group
Group Leader: Dr. Christopher Kley
Our research group focuses on material synthesis and nanoscale understanding of solid-liquid interfaces for applications in catalysis and energy conversion. Key catalytic reactions, including CO2 conversion, are challenged by the degradation of the materials employed under operation conditions, performance-limiting inefficiencies at catalyst-electrode interfaces, and limited selectivity and efficiency of the catalysts for multi-electron and proton-coupled transformations. more
Scanning Probe Microscopy
Group Leader: Dr. Markus Heyde
Our research is focused on high resolution imaging and spectroscopic characterization to significantly improve our understanding of surface structure and chemistry of complex materials. The main experimental tools are low temperature ultra-high vacuum non-contact atomic force and scanning tunneling microscopy. They allow us to characterize surface structures ranging from periodic and ordered surfaces to more defective morphologies and amorphous networks. more
Spectro-Microscopy
Group Leader: Dr. Thomas Schmidt
Our investigations focus on the preparation and modification of thin oxide films on metal supports and metal nanoparticles on oxides and on the structural, electronic and chemical properties of these systems for thermal catalysis. The experiments are performed with the high resolution spectro-microscope SMART (Spectro-Microscope with Aberration Correction for many relevant Techniques) operating at the BESSY II electron storage ring. more
Structure and Reactivity
Group Leader: Dr. Shamil Shaikhutdinov
We study surface chemistry of oxide-supported metal and transition metal oxide nanoparticles focusing on the effect of the particle size, shape and the nature of oxide support on reactivity, particularly in CO2 hydrogenation reactions. more
Thin Films
Group Leader: Dr. Helmut Kuhlenbeck
The activities of the group are centered around thin film catalyst models. Such models mimic relevant aspects of a real world catalysts, but have a reduced complexity. That allows us to understand catalytic processes in detail. Central activities of the group are the development of thin film preparation recipes and the study of thermal and electrocatalytic reactions at the thin film / gas or liquid interfaces. more
