Project

CO2 conversion to plastics using electrochemistry

Publisher

Supervisor

Location

Greater Copenhagen area

In this project you will use electrochemical techniques to convert CO2 into ethylene, which is the main precursor in polyethylene, the most popular type of plastic used today.The overall purpose of this project is to mitigate CO2 induced global warming by taking CO2 from powerplants, cement plants, and other sources and converting it to useful chemicals so it doesn't get vented to the atmosphere.

This project will be a joint project between Siemens and DTU Physics.  The goals will be to bridge the gap between the fundamental discoveries at DTU Physics (we already have great catalysts) and the large scale (hydrogen) electrolysis knowledge from Siemens. We just need to bridge the two.

We have recently built and calibrated an electrochemical test reactor, so this project primarily would involve creating new catalysts based on existing knowledge from DTU Physics and testing their performance under realistic operating conditions such as elevated temperatures and pressures. In the reactor CO2 will be electrochemically reduced to ethylene and water will be oxidized to oxygen.  A key performance indicator will be the reaction rate and selectivity at a given electrochemical potential.

From this project you will learn skills general skills in reactor engineering design, catalyst preparation and optimization, electrochemical testing techniques such as cyclic voltammetry, chronoamperometry, product analysis using gas chromotography, NMR, and/or mass spectrometry, and materials analysis skills such as x-ray diffraction, x-ray photoelectron spectroscopy, and electron microscopy techniques.

The work will be carried out both in the SurfCat section of DTU Physics and Siemens (located at DTU Scion). The SurfCat section of DTU Physics has well funded, world-class equipment and infrastructure, multiple PhD level technicians to help out, and a large interconnected knowledge base of professors, post-docs and PhD students.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
