In the Team “Dynamic Non-Equilibrium Processes”, we investigate dynamic processes that take place out of equilibrium conditions. In particular, we are interested in resolving the molecular reaction mechanisms (under near-reaction conditions). This involves recording “molecular movies”, in which experimentally atomically resolved motion pictures of the reactions are recorded, including the structural and chemical identification of the intermediate states and transition states. Since these phenomena take place on the femto- to picosecond scale, ultrafast experimental methods are required, and X-ray free-electron lasers for ultrashort X-ray pulses have recently become available. The focus is on thermocatalytic (de)hydrogenation reactions and electrochemical interfacial reactions.
