CO2 electrolysis is an excellent approach to use society’s dominant greenhouse gas as a means to provide the base chemicals such as CO, ethanol, and ethylene on which the chemicals industry is built.  While CO2 electrolysis allows for a wide variety of carbon-based products, we still do not have control over the selectivity and the activity still needs improved. 

This project will look to improve the selectivity and activity of CO2 electrolysis catalysts with the focus being on highly reduced products (i.e. greater than 2 electron transfer reductions). In particular, we will look to shift selectivity towards acetaldehyde and ethanol and away from ethylene and acetate. This position will primarily be applied in nature, thus significant focus will be on gas diffusion electrode (GDE) type reactors and the integration of catalysts, gas diffusion layers, ionomers and membranes.  The highly technical side of operating such a complex device as a GDE reactor often hides the scientific principles driving the reaction.  Thus a large part of this project will involve designing ways to maximize the amount of characterization we can achieve from a GDE reactor. Only with a strong understanding of what is taking place within the reactor, can we then modify the catalyst, ionomer or operating conditions to optimize selectivity to ethanol.

At DTU Physics we already have three gas diffusion electrode reactors with in-line gas chromatography (GC) and ex-situ HPLC, thus you will be able to build off an already operational system.  Validation of our results is essential thus our set-ups are designed to measure both anode and cathode products.  Control of temperature, pressure, and humidity are all parameters we are in the process of integrating into our device, and we would expect you to be involved in this area as well. Thus, strong engineering competencies are needed.

As part of this project there is also the possibility to focus on fundamental studies as well.  We are significantly involved both experimentally and theoretically in discovering new alloy catalysts, thus there is the possibility to get involved in this aspect.  We already have multiple H-cell reactors in-line with gas chromatographs allowing for a quick start to any new catalyst development.

The project is funded by the SELECTCO2 and will take place at the SurfCat laboratories at DTU Physics. In these laboratories we have 3 Sniffer chip devices, 25 potentiostats, 4 RDE set-ups, 5 standard gas chromatographs and 1 GC-MS, 2 magnetron sputter chambers, 2 mass-selected cluster source devices, 5 XPS (one with in-line electrochemical set-up), 3 gloveboxes, 2 XRD set-ups (one allowing in-situ annealing with gas flow), ICP-MS, FTIR, 3 full time technicians, and a sufficient number of wet-labs, fume hoods, and furnaces. We also have access to clean room facilities and electron microscopy via DTU Nanolab, as well as a consultant on innovation who has helped start up 3 start-ups in the last 8 years from the SurfCat section of DTU Physics.

Qualifications
It is essential that the successful candidate is highly ambitious as well as open minded and willing and able to work as part of a team. The candidate should have a PhD degree in Physics, Chemistry, Chemical Engineering, Material Science or a similar field or will expect to have that degree within the immediate future. The candidate should have extensive experimental experience working with electrocatalytic reactions, and working with CO2 electrolysis would be highly beneficial.
