Functieomschrijving

A holy grail in the field of catalysis is to obtain exact insight in the reaction mechanism such that we can design more effective catalysts. This is more important than ever as we need to transfer to sustainable energy, and produce useful chemical and materials from a sustainable feed stock. Exact insight in the reaction mechanism will enable this revolution in chemistry.

So far, heterogeneous catalysis can only be followed on time scales that are too slow to detect the actual conversion of reactants: the bond breaking and forming and the intermediate species. The limitation is the speed by which a reaction can be turned on (for example via a rise in temperature or via addition of reactants). In this project you will use a method to generate heat extremely fast namely at the picosecond time scale by the use of femtosecond pulses of light. You will show that you can use this method, in an adapted pump-probe spectroscopy scheme, to gather spectra on the picosecond to microsecond time scale after kickstarting the reaction. You will benchmark the method with a test reaction (hydrogenation by supported Platinum). Specifically, you will gather ultrafast mid-infrared and X-ray absorption spectra, as they provide the most information on the intermediate chemical species. The goal is to actually 'see' the bondbreaking, the bond forming and the subsequent formation of different intermediate species.
