Electrocatalysis and Interfaces Group

Our motto: A place where diversity lives, and sustainable energy is what it gives

drop

The Electrocatalysis and Interfaces Group was established at PSI in 2012 and is now under the joint leadership of Prof. Thomas J. Schmidt and PD Dr. Emiliana Fabbri.

Our research activities focus on understanding the mechanisms of various electrochemical energy conversion reactions at solid-liquid interfaces. We aim to apply this fundamental understanding to the design of novel electrocatalysts for the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution/oxidation reaction (HER/HOR), CO2 reduction reaction (CORR), and urea electrosynthesis.

To optimize the rate, selectivity, energy efficiency and stability of these electrochemical reactions, appropriate catalysts must be designed and optimized. Our research studies include the synthesis of nanostructured materials, precise electrochemical characterization, and investigation of the physicochemical properties of the electrocatalysts under operating conditions using advanced X-ray-based operando spectroscopy. The most promising electrocatalysts developed by our group are often tested at the single cell level in (co)electrolyzers or fuel cells.

Through collaborative understanding, discovery, and creation, we will empower a future where science tackles society's greatest challenges and inspires a diverse generation of innovators.

 

Understand, Discover,  and Create

  • We strongly support the role of science in the development of society. Our research goals push the boundaries of science to create new values to address the major challenges facing our society: sustainable energy, climate changes and circular economy.
  • We transfer fundamental discoveries into practical technologies.
  • We enable our scientific excellence through collaboration.

 

Inspire and Educate

  • We aim to provide a stimulating environment and an open learning space.
  • An inclusive working environment and safe working conditions are essential for the professional development of our group members.
  • We strive for: gender equality, high diversity (cultural, educational, gender), constructive team interaction, methodical & logical thinking, self-motivated team members and a supportive team environment.
We harness the power of cutting-edge electrocatalysis research to unlock a clean and sustainable energy future by efficient electrochemical processes.

 

  • Pushing the boundaries of science through cutting-edge research on electrochemical energy conversion reactions, we strive for a sustainable society based on a clean and environmentally friendly energy system.
  • Our goal is to understand reaction mechanisms, catalyst property/activity relationships, and design principles for various electrochemical reactions in order to develop better performing, longer lasting electrocatalysts.
  • We aim to bridge the gap between fundamental science and application, ranging from model systems to device implementation (single cell MEAs).
From model systems to device implementation.

 

  • Focus on technologies of future relevance.
  • Material concept to device implementation TRL 1 – 2.
  • Exploiting the possibilities of PSI’s large facilities.
