Associate Professor- catalysis engineering
Van 't Hoff Institute of Molecular Sciences, University of Amsterdam.
In two new LIFT projects, we will develop graphene based coatings together with Tata Steel-Netherlands and chemical intermediates based on polycyclic aromatics with Reutgers resins:
Other partners in the consortium include the University of Castilla-La-Mancha (UCLM, Spain), the Technological Educational Institute of Sterea Ellada (TEISE, Greece) and the Chemical Process Engineering Research Institute (CPERI, Greece).
Three companies are involved: Hellenic Petroleum Renewables (HELPE RES, Greece), GRAPHENANO (Spain), and Delft Solid Solutions (Netherlands).
We have discovered a new catalyst for ammoximation.This catalyst contributes to more sustainable processes for making fine chemicals and pharmaceutical intermediates and for polymer production. The University of Amsterdam (UvA) has transferred the patent and all related intellectual property rights on this catalyst to DSM.
I won the UvA Science Park New Ideas Prize contest 2010, together with Gadi, for the finding of 'A new catalyst for making nylons'. This new catalyst and process gives a straightforward route to making nylons that reduces waste and demands less raw material. The catalyst has also been patented by the University of Amsterdam. We are now in contact with possible industrial partners in an effort to turn the discoveryinto a commercial process.
Our work has been featured by the University of Amsterdam in this video:
I am also a managing council member of the COST (European Cooperation in Science and Technology) Action CM1104 Reducible oxide chemistry, structure and functions.
Using a simple and straightforward approach, we have created a bifunctional surface that combines the advantages of bifunctional enzyme-like catalysis with the ease of separation and robustness of traditional heterogeneous catalysis.
( Angew. Chem. Int. Ed. 2011, 50, 9615 -9619)
We are also working on various routes for converting renewable feed-stocks (glycerol, lactic acid) to chemicals.

We also try to understand how a catalyst works for a reaction, using advanced spectroscopy/microscopy techniques such as XAS, XPS, aberration corrected electron microscopy, solid-state NMR and so on. See, e.g., Shiju et al, J. Am. Chem. Soc., 130 (2008) 5850 (propane ammoxidation to acrylonitrile over mixed oxide catalysts).
