We are currently looking for a postdoctoral researcher (f/m/d) for the electrochemistry group at the Department of Interface Science.
The Haber-Bosch process uses elevated pressures, temperatures and iron-containing catalysts to fixate nitrogen with the help of hydrogen into NH3 – the key ingredient of fertilizers, transferring nitrogen from the air into our soils. If the required H2 could be produced via CO2-neutral steam reforming or water electrolysis, ammonia would expand its role from being a chemical carrier of nitrogen to transporting and storing green hydrogen. Reversing the Haber-Bosch process, the hydrogen could be released from NH3 sustainably via ammonia fuel cells and the electrochemical ammonia oxidation reaction (AOR) could also lead other valuable products of industrial interest. Past studies have largely focused on the exact AOR mechanism and competing catalyst deactivation pathways on noble metal surfaces for the production of H2. However, NH3 is also an important ingredient in the chemical industry to produce other key molecules. So far, no focused efforts have been undertaken to use the electrochemical AOR for direct and sustainable conversion of NH3 into feedstocks for the chemical industry.
Within this two-year project, you will study the electrochemical AOR with the goal of hydroxylamine (H2NOH) formation in cooperation with BasCat, the UniCat BASF JointLab.
The PostDoc position is initially limited to two years.
