Ueli K. Heiz

Prof. Ueli K. Heiz is a Professor and Principal Investigator at the Technical University of Munich (TUM), leading the Cluster Catalysis and Advanced Spectroscopy group within the Department of Chemistry. His research focuses on the unique properties of atomic-scale clusters in the non-scalable size regime, exploring their applications in catalysis (nanocatalysis, asymmetric catalysis, photocatalysis) and energy conversion. He develops advanced experimental tools like ECSTM (Electrochemical Scanning Tunneling Microscopy) and UHV (Ultra-High Vacuum) systems for studying cluster dynamics and reactivity.

Key research areas include clusters at solid-liquid interfaces, gas-phase cluster kinetics, and ambient pressure photocatalysis. His group investigates how quantum size effects and precise atomic structures influence catalytic performance. Associated with TUM’s Chair of Physical Chemistry, his work bridges fundamental chemistry with practical applications in sustainable energy technologies. The group collaborates with initiatives like the Munich Catalysis Alliance (MuniCat) and operates specialized facilities such as the Magnetron Sputtering Cluster Source and Spectroscopy labs.

His research has led to advancements in understanding reaction mechanisms on size-selected clusters, including methane coupling, alcohol photocatalysis, and enantiospecific surface interactions. Funding sources include the Collaborative Research Centre (CRC) and other institutional grants. While no personal awards are explicitly listed, his contributions to catalysis and spectroscopy methodologies are highlighted through high-impact publications in Journal of the American Chemical Society and Angewandte Chemie.
