Autor: Eva Kratzer, Simon Schötz, Sven Maisel, Dominik Blaumeiser, Sharmin Khan Antara, Leon Ewald, Daniel Dotzel, Marco Haumann, Andreas Görling, Wolfgang Korth, Andreas Jess, Tanja Retzer

Publikováno v: Catalysis Science & Technology. 13:2053-2069

We apply supported ionic liquid phase (SILP) catalysts to hydrogenate small 1-alkenes in a continuous fixed-bed reactor. We rationalize the origin of catalyst decomposition via IR spectroscopy and adapt the catalyst design for improved stability.

Thermal Stability and CO Permeability of [C4C1Pyr][NTf2]/Pd(111) Model SCILLs: from UHV to Ambient Pressure

Autor: Roman Eschenbacher, Simon Trzeciak, Christian Schuschke, Simon Schötz, Chantal Hohner, Dominik Blaumeiser, Dirk Zahn, Tanja Retzer, Jörg Libuda

Publikováno v: Topics in Catalysis.

Solid catalysts with ionic liquid layers (SCILLs) are heterogeneous catalysts which benefit significantly in terms of selectivity from a thin coating of an ionic liquid (IL). In the present work, we study the interaction of CO with a Pd model SCILL c

Hydrogen Production Based on Liquid Organic Hydrogen Carriers through Sulfur Doped Platinum Catalysts Supported on TiO2

Autor: Regina Palkovits, Tanja Bauer, Ximeng Chen, Jörg Libuda, Dominik Blaumeiser, Simon Schötz, Christian Henning Gierlich

Publikováno v: ACS Sustainable Chemistry & Engineering. 9:6561-6573

In order to move from a carbon-based energy system to a more sustainable one, focus is put on liquid organic hydrogen carrier (LOHC) systems for CO2-free hydrogen storage and release. In this study...

Enhancing the feasibility of Pd/C-catalyzed formic acid decomposition for hydrogen generation – catalyst pretreatment, deactivation, and regeneration

Autor: Dominik Blaumeiser, Simon Schötz, Andreas Bösmann, Peter Wasserscheid, Tanja Bauer, Patrick Preuster, Axel Kosider, Jörg Libuda

Publikováno v: Catalysis Science & Technology. 11:4259-4271

Formic acid decomposition (FAD) generates H2 at low temperatures. However, many known catalyst systems suffer from deactivation due to competing side reactions during FAD. In this work, we focus on the origins of the deactivation of Pd catalysts but

The water gas shift reaction (WGSR) is catalyzed by supported ionic liquid phase (SILP) systems containing homogeneous Ru complexes dissolved in ionic liquids (ILs). These systems work at very low temperatures, that is, between 120 and 160 °C, as co
