The Department of Energy Conversion and Storage, Technical University of Denmark (DTU), invites applications for a PhD scholarship in characterisation of new electro-catalysts enabling electrochemically driven ammonia synthesis.
The research project is part of the project “Progress” recently funded by the Independent Research Fund Denmark. The project involves collaboration with Copenhagen University, Max Planck Institute in Germany and University of Lund, Sweden.
Transforming our society to rely only on sustainable energy sources is a massive challenge. Key to success will be development of cost competitive routes to produce hydrogen via electrolysis of water/steam driven by green electricity. The hydrogen has value in itself but may, importantly, also serve as a reactant for production of ammonia. Ammonia has great importance as a fertilizer, but can also be an “energy vector” enabling emission reduction from “hard to electrify” sectors like global shipping. Hence, cost competitive routes to “green hydrogen” and “green ammonia”, not relying on use of natural gas, is in high demand.
The ambition in “Progress” is to facilitate integration of the hydrogen production step and the ammonia synthesis step to enable an efficient route to ammonia driven only by electrical energy. If the solid oxide cell applied is a proton conducting ceramic, controlling the potential and current allows control of the hydrogen activity at the electrode surface. It is the hypothesis behind the project that careful control of this and possibly cycling it may enable an overall more efficient process.
In parallel with the experimental endeavors, which is the core of the announced Ph.D. project, the project involves a modelling effort carried out at Copenhagen University to describe the kinetics of the electrode reaction.
Responsibilities and qualifications
The successful candidate will work on suggesting and characterising new materials for the cell cathode – both for the electrochemical active phase and for possible catalysts to be added. The work will involve development of cell architectures that can enable a study of reaction intermediates during operation (e.g. XPS, Raman) the overall purpose being to identify the rate limiting steps of the reaction.
Key tasks will be:
- Synthesis of candidate materials and characterisation of their fundamental charge transport and catalytic properties.
- Preparation of electrodes and electrochemical characterisation of performance.
- Developing tailor made electrode/cell-geometries that enables study of the reaction in operando (via e.g. Raman or XPS).
You will collaborate with colleagues in the section for Solid State Electrochemistry doing materials synthesis and cell characterisation as well as with the colleagues from Copenhagen University in charge of the modelling efforts in the project.
As part of the PhD education, you will follow courses and assist in teaching activities
- You are expected to spend at least 3 months abroad at one of the partnering institutions listed above,
- You will disseminate your work in international peer reviewed journals and at professional conferences.
Candidates should have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.
We favour candidates with a degree in chemical engineering, chemistry, materials science, physics or a similar degree with an academic level equivalent to a master’s degree in engineering. Experience with one or more of the following areas is considered an advantage;
- Heterogeneous catalysis and/or electrochemistry
- Experimental characterization of chemical reaction kinetics
- Materials synthesis and characterization
- Raman, XPS, Electron microscopy.
Moreover, the successful candidate
- is innovative and able to work in cross-disciplinary teams
- has good communication skills in English, both written and spoken
- is able to work independently and take responsibility for the progress and quality of projects.
Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU’s rules for the PhD education.
