Abstract：

Understanding catalysis, and in particular heterogeneous catalysis, has been based on the investigation of model systems in combination with theory. We have developed strategies to prepare such model systems based on single crystalline oxide films, which are used, as reactive media, as support materials, as well as permeable covers to study reactions in confined space. The talk will cover some of the topics touched upon in the later years of my directorship, such as CO2 activation on supported Au nanoparticles, surface action spectroscopy and using 2D silica films to study reactions in confined space.
