Electron transfer processes within (bio)electrocatalysts and on the electrode/catalyst interface at the molecular level.
Our research
We aim to enhance the understanding of electron transfer processes within (bio)electrocatalysts and on the electrode/catalyst interface at the molecular level, and to design new (bio)electrocatalytic devices based on this new understanding. Our research bridge the disciplines of electrochemistry and (bio)inorganic chemistry and utilizes a range of electrochemical, spectroscopic and theoretical techniques, including single entity electrochemistry, protein film electrochemistry, electron paramagnetic resonance spectroscopy and quantum mechanical calculations, to address fundamental question of relevance to electrocatalysis.
Our current work focuses on investigations of plasmon-driven electrocatalysis at single plasmonic nanoparticles and on development of new single-molecule electrochemical techniques for studies of enzymatic catalysis, particularly focusing on oxygen reduction reaction catalyzed by multicopper oxidases. Other collaborative work include mechanistic studies of hydrogenase catalysis by protein film electrochemistry and examination of heme-based biomimetic catalysts by electron paramagnetic resonance spectroscopy.
