Forschungsbereich - Elektrokatalyse

In diesem Forschungsbereich werden grundlegende elektrochemische Reaktionen an Modellelektroden untersucht, um hieraus Einblicke in die Beziehung zwischen Elektrodenstruktur und dessen Aktivität zu erhalten. Aus dem Verständnis der Reaktionsmechanismen lassen sich Ansätze zur Verbesserung der Aktivität, Effzienz und auch der Stabilität elektrochemischer Prozesse ableiten.

Theorie

While experimental studies on electrocatalytic reactions are often limited in their ability to identify reaction mechanisms, intermediates and/or the energetics of individual steps, combining such studies with corresponding theoretical investigations is indeed capable to provide in-depth insights into electrocatalytic processes and to assist the improvement or even the development of new electrocatalysts.
Using our multi-scale approach that combines quantum-mechanical methods with forcefield and meso-scale (e.g. kMC) approaches, we investigate the fundamental steps of electrocatalytic reactions, including the HER/HOR, OER/ORR as well as the formic acid oxidation and CO2 reduction.
To allow for a tight connection with experiments we usually concentrate on model systems, such as single-crystal surfaces, and afterward extend our studies to process-relevant catalysts (e.g. nanoparticles or structured catalysts.
