PhD - student Femtosecond Electrochemistry

Work Activities
The world is facing a tremendous challenge in limiting global warming resulting from the burning of fossil fuels. Over the last decades, a lot of progress has been made in the harvesting of sustainable energy by solar panels and wind turbines. However, to truly establish an energy-sustainable society, we also need to store sustainable energy in an efficient manner, i.e. by transferring the electricity produced by the sun or wind into high-energy chemical compounds like hydrogen or methanol via electrochemical process. This constitutes a very important challenge to solve: present electrochemical devices have very low efficiencies and can often not be scaled up to convert large quantities of energy. Hence, there is a great need to create novel electro-chemical devices that are much more efficient in storing sustainable energy and that can be used at a large scale. To this purpose, we need to acquire a much better fundamental understanding of the working mechanism of electro-chemical devices.
In this project you will study the molecular structure of aqueous electrolyte solutions near electrode surfaces using advanced ultrafast spectroscopic techniques. One of these techniques to be used is femtosecond surface sum-frequency generation. The signal measured with this technique provides direct information on the nature of the vibrations of the molecules near the surface and on the orientation of the molecular groups carrying the vibrations. As a result, we can acquire detailed understanding of how the structure of the water molecules and dissolved molecules and ions close to the electrode surface depend on the composition of the solution, the nature of the electrode material and the applied bias to the electrode. In a next step we will study the dynamics of the water molecules and the dissolved molecules while the electrochemical reaction takes place. We will identify the reactive intermediate with time-resolved surface sum-frequency generation.
The research work will be carried out in close collaboration with other PhD students and post-docs within the Ultrafast Spectroscopy group of Prof. dr. H.J. Bakker. In this project we will also work closely together with the Theory group of Dr. B. Ensing at the University of Amsterdam and the electro-chemistry group of Prof. dr. M. Koper at the University of Leiden.
