Seger Research

I am currently a full professor in the Surface Science and Catalysis section at the Physics Department at the Technical University of Denmark (DTU). Our research focuses on using the power derived from sustainable energy sources (i.e. wind and solar) and using this to electrochemically drive reactions to high value chemicals and fuels.  I am heavily involved in the Villum Center for Sustainability (VSustain) and the Pioneer Center for Accelerating P2X Materials Discovery (CAPeX) , thus a significant amount of my research is tied in to the focus of this center as well.  To contact me my email is

My research is focused on accelerating the transition from a fossil fuel and chemical based society to one that is based on sustainable energy and chemicals.  To understand where we are now, and where we need to be, see my powerpoint I use for the introductory lecture to my Physics of Sustainable energy course here. Into the details, my research relates to various electrocatalytic reactions primarily related to CO2 electrolysis to various organic chemicals (see motivation), but also including water electrolysis and partial oxidation reactions.
CO2 Electrolysis

My research can be broken down into various forms of electrocatalysis both in terms of reductive reacitons, oxidative reactions, and electrochemical device analysis.   Click on one of the links below to learn more about one these focuses.
Fundamental  Electrolysis Reaction Environment in Scalable Devices Synchrotron Based Analysis
With CO2 and water can produce between 8-14 different products, almost all a higher value than hydrogen.  However we would like to isolate a single product, so we need to understand the mechanism for these products. This will also allow us to find what properties we need in any new catalyst to achieve better performance. The catalytic environment in commercially relevant devices is not always the same as with fundamental studies. The reaction environment in scalable devices can be quite different, meaning we both need to discover the science of what is actually happening, and then use fundamental knowledge to help optimize perfromance within the engineering constraints. Organic electrolysis produces a wide variety of products with highly sensitive selectivity.  Actually seeing what is going on in commercial devices is challenging.  By using high powered x-ray from synchrotron facilities we can use a multitude of analysis techniques to allow us to 'see' in the reactor while it is operating.  This allows us to first establish the science, and based on this, vary parameters to optimize performance.
