Concentration gradients are frequently present when applying heterogeneous catalysts in liquid phase because of relatively slow diffusion. The consequence is loss in performance and/or falsification of kinetic information. Therefore we synthesize and test new structured supports in order to prevent significant gradient both at the external surface as well as in the internal pores of the catalyst support and work towards in-situ characterization of liquid phase catalyis. Here you find an overview of our research in liquid phase catalysis.
Kinetics of nitrite hydrogenation – Pd particle size and support effects are studied by using PVA stabilized Pd colloids.
Water purification – the removal of NOx- from drinking water is studied in newly designed reactors and with organic reductants.
Reversible loading of catalysts – the entangling properties of carbon nanofibers are utilized to reversibly lead catalysts in structured reactors for three phase reactions.
Wettability of CNF surfaces – the structural factors which determine the wettability of CNF surfaces are investigated.
The hydrophobicity inside support materials is changed in order to direct gas and liquid flows within the support.
