Electrocatalysis and Interfaces

The Electrocatalysis and Interfaces Group was established in 2012 combining the electrocatalysis activites of the former Fuel Cell Group and the Interface analytical activities of the former Interface and Capacitor Group.
Electrocatalysis is the key topic for electrochemical energy conversion. In order to optimize rate, selectivity, energy and stability of a certain electrochemical reaction - such as oxygen reduction, oxygen evolution, hydrogen oxidation, and CO₂ reduction - proper catalysts have to be developed and optimized. The respective surface and interface analytical tools are essential for the understanding of the catalyst and are utilized in the group.

Therefore the activities of the group cover two focal points - Electrocatalysis and Interface analysis including Electrochemical capacitors.

Electrocatalysis - opens new routes towards more efficient fuel cells and other electrochemical processes e.g. CO₂ reduction. The group's main topics are investigations of the effect and utilization of oxides as support for O₂ reduction catalysts and the optimization of CO₂ reduction catalysts. Catalysts for electrolysis and reversible fuel cells are also studied in our group.

Interfaces - Surface analysis is essential for the understanding and optimization of catalytic and electrochemical interfaces and provides information about processes and electronic and molecular properties on a microscopic scale. The main topics at present are catalysis of nano particles and electrocatalysis. We also developed in situ UHV electrochemical cells for in situ studies of the electrolyte|electrode interface, in particular the ionic liquid | electrode interface.

In addition we provide support for customers within and outside PSI.
