Analysis of samples for CO2 hydrogenation

In this experiment, we want to measure Zn and Cu K-edges on six samples for CO2 hydrogenation. The samples are grouped into two sets: one is laboratory-prepared, and the second one is commercial. Each set is made of three samples: the first one is as prepared, the second one has been activated in H2, and the last one has followed a catalytic reaction in H2/CO2. The samples will be prepared as pellets and measured in transmission mode under a normal atmosphere.
The experiment aims to observe whether there are changes in the copper and zinc coordination/surroundings after the reactions, and when present, if these changes can be observed both in the industrial and laboratory-made samples.
