Nanoscale electrochemical reactivity

Electrocatalysis

To rationally design electrocatalysts, detailed understanding of the interrelation between the electronic and atomistic structure of specific surface sites and their chemical reactivity is required. For example, the influence of domain boundaries between different catalytic materials or the importance of step edges in contrast to terraces has to be further elucidated on the (sub-)nanometer level. We employ a variety of state-of-the-art electrochemical spectroscopy methods to characterize electro-active surface sites and the site-specific and potential-dependent pathways of electrocatalytic processes to pave the way for the development of improved electrocatalysts.
