Electrochemical Energy Conversion
Alexander K. Opitz’ research follows an application-inspired approach to address fundamental scientific questions of solid state electrochemistry and electrode kinetics. By integrating electrochemical investigation techniques such as impedance spectroscopy with in-situ analytical techniques, he aims to elucidate reaction mechanisms on oxide electrodes. This integrated approach allowed for example to provide mechanistic explanations for phenomena such as the acceleration of reaction kinetics on mixed-conducting electrodes through currently intensively explored ‘exsolution catalysts’.
Another feature of Alex Opitz’s research group involves acquiring an understanding of current and reaction pathways, as well as the electrochemically active regions within solid-state electrochemical systems. This is achieved through the preparation of well-defined model systems, predominantly utilizing micro-structured thin films. By transferring the gained knowledge to ‘real’ 3D porous electrodes, their complex behavior can be understood on the level of physical elementary parameters, as already demonstrated in successful collaborations with partners from the industry.
