Interface Science Department

Our department investigates the unique structural, electronic, vibrational and chemical properties of size- and shape-selected nanostructures and thin films and their interfaces with gas and liquid environments.

Understanding the interplay between the numerous factors determining the physico-chemical behavior of such systems is crucial for optimizing their efficiency for applications in catalysis and more specifically in energy conversion. To this end, advanced synthesis methods and in situ / operando surface/bulk-sensitive characterization techniques are being employed in our department for the fundamental understanding of catalysts “at work”.

A team of researchers from the Department of Interfacial Sciences has discovered how changes in the structure of copper catalyst particles during electrochemical CO2 reduction affect their catalytic performance. This should lead to the development of new catalysts that convert the greenhouse gas CO2 into useful chemicals.
