The goal of Geert-Jan Kroes is to achieve the ability to predict the outcome of dissociative chemisorption reactions of small molecules on transition metal surfaces. This requires an accurate modeling of the molecule-metal surface interaction and of the reaction dynamics, including energy dissipation.

Biography

My father studied chemical technology at the Technical University of Delft, so my interest for chemistry is in the genes! I became really interested in chemistry when it became clear to me that it is also possible to simulate chemical reactions, using computers. In this context, I am interested in the dynamics of chemical reactions. How fast are chemical reactions? And how do the forces between the atoms influence specific reactions? The topic I focus on concerns reactions of molecules at metal surfaces. My passion and career goal is to eventually achieve a chemically accurate description of dissociative chemisorption on metal surfaces. I believe this has been accomplished for systems with (WF-EA) > 7 eV, where WF is the work function of the metal, and EA the electron affinity of the molecule. The next step is to now also accomplish this for systems with (WF-EA) > 7 eV.

These systems are prone to electron transfer, and therefore to electronically non-adiabatic effects like electron-hole pair excitation. Additionally, these systems are hard, if not impossible, to describe with the standard (GGA and meta-GGA) density functionals of DFT. It is my belief that, to make real progress with these systems, the specific reaction parameter approach to density functional theory (SRP-DFT) has to be put on a first principles basis. Furthermore, progress needs to be made with the accurate treatment of electronically non-adiabatic effects on molecule-metal surface reactions. My group is working along these two directions.
