Area B ‘Interface-enhanced SILP’ focusses on dissolved molecular catalyst complexes that show a very high preference to be located at the interfaces of ‘Supported Ionic Liquid Phase (SILP)’ systems. The interface affinity should be a function of the applied ligands, support chemistry, ionic liquid, and gas phase. Our research target is to elucidate and exploit the specific reactivity located at both, the gas/liquid and the liquid/solid interface.
