The project deals with the new synthesis of Cu/ZnO/Al2O3 hydrogenation/dehydrogenation catalysts, enabling controlled embedding of active copper sites in ZnO/Al2O3 matrix having a hydrotalcite structure. The starting precursors and the final catalysts will be thoroughly characterized to determine the catalyst’s structure and properties. Special attention will be paid to the active copper sites, their structure, and the effect of their surroundings on their activity and selectivity. The characterization will rely on a combination of in-situ techniques with theoretical modeling of the structure and properties of the active copper centers and their ZnO/Al2O3 interface. Finally, the performance of the synthesized catalysts in model hydrogenation (hydrogenation of CO, CO2, and furfural) and dehydrogenation (ethanol and cyclohexanol dehydrogenation) reactions will be evaluated. The activity, selectivity, and stability of the catalysts will be related to the determined properties and structure, including the geometry of the active sites.

Aims
The goal of the project is to describe the relationship between synthesis conditions, properties of the novel Cu/ZnO/Al2O3catalysts, including the structure/interface of the catalytically active sites and their catalytic activity in model hydrogenation and dehydrogenation reactions.
