The formation of propanol over supported Au catalysts with a carbon dioxide feedstock
A Ultra-high Vacuum (UHV) chamber was designed, built, and tested in order to examine the binding of CO2 on a Au surface. An X-Ray Electron Spectroscopy (XPS) apparatus was added to evaluate the atomic composition and oxidation state of the adsorbed gas. Additionally, a high-pressure fixed bed flow reactor was designed, built, and tested to enable the Reverse Water-Gas-Shift Reaction necsessary to produce CO to then couple with ethylene to form propanol. These apparatuses create a feedback loop in order to test and tune catalysts to maximize conversion of CO2 while maintaining propanol selectivity.
