Electrochemical Instabilitites

Electrochemistry is resourceful field for investigators of complex systems. Temporal oscillations and spatial patterns (position dependent reaction rate distribution over the electrode surface) have been observed during electrodissolution, electrodeposition, and electrocatalytic reactions.
The complexity in this reaction system arises from the counterplay of chemical and physical processes.

We investigate the effects of self-organization (such as oscillation, bistability, and formation of spatiotemporal patterns) on the reactive properties of electrochemical systems. These systems include metal (copper, nickel, iron) dissolution in acidic solution, CO/H
2 electro-oxidation, and electrodeposition.
