We are dedicated to innovative chemical technologies and thrive at the interface of heterogeneous catalysis, reaction engineering, downstream processing as well as conceptual process design.
Our research focuses
(I) on the utilization of renewable resources (biogenic platform chemicals and carbon dioxide) for sustainable chemical production as well as
(II) on porous and functional materials as innovative catalysts, adsorbents and membrane materials.
