O 45: Focus Session: Catalysis at Liquid Interfaces

Mittwoch, 7. September 2022, 15:00–18:00, H4

Catalysis at liquid Interfaces has emerged as novel approach to explore the highly dynamic, anisotropic environment of liquid interfaces to create, tailor, and stabilize catalytically active sites with unique reactivity and performance. With this concept, fundamental problems of catalyst science and technology can be addressed to develop novel catalytic materials that combine selectivity, productivity, robustness, and ease of processing at the highest possible level. Thus, the concepts of "Supported Catalytically Active Liquid Metal Solutions" (SCALMS), interface-enhanced "Supported Ionic Liquid Phase" (SILP) and advanced "Solid Catalysts with Ionic Liquid Layer" (SCILL) systems are of particular focus.
