Electroactive organic compounds and their metal complexes are at the heart of our research. To decipher their electron transfer properties, we usually use a combination of CV and DPV. The same methods are also used to investigate electrocatalytic processes such as H2 activation and production, CO2 reduction and C-C bond formation reactions. Additionally, bulk electrolysis is used for studying the electrocatalytic reactions. An important current focus is the use of electrochemical methods for the investigation of reaction mechanisms of electrocatalytic reactions.
