The long-term deactivation of CO2 hydrogenation catalysts will be measured under high-pressure with operando X-ray diffraction, X-ray absorption spectroscopy and vibrational spectroscopy.
With the rising CO2 levels, a lot of research has been going into finding ways of utilizing this industrial waste product. After being captured from the air, carbon dioxide can be catalytically converted to any number of products such as methanol and higher value alcohols.
In order to rationally synthesize the required catalysts, the deactivating effects have to be investigated. This can be done with X-ray analysis techniques such as XRD and XAS under operando conditions. However, these experiments often require access to a synchrotron, which limits catalyst evaluation time.
The goal of this project is to work with lab-based setups to allow for operando XAS/Raman/IR and operando XRD/Raman/IR measurements, targeting long-term (>3 months) catalyst assessments. This project will expand upon state of the art reactors to facilitate higher operational pressures.
