Offer Description

It is understood that the local properties of a given electrode-electrolyte interface (e.g., pH, specific adsorption of molecules, nature of the ionic species) have critical influence onto the reactivity and durability of electrochemical systems. This so-called 'local reaction environment' is greatly impacted by both the reactions taking place at the interface and by the morphological properties of the latter. Thus a model flat electrode and a tri-dimensional, nanostructured, multi-phase interface will have notably different local environments. The local and morphological properties also impact the distribution of the reaction rates at the elec-trochemical interface. To optimize the future generations of electrochemical systems, they should be understood. Within this project, we aim to study different types of electrochemical interfaces (e.g., model, nanostructured, tri-dimensional, etc.) that are of interest for the hy-drogen cycle and, more specifically, to focus on (i) the pH and ionomer distribution at the electrode-electrolyte interface and on (ii) the impact of said distribution, of the ionomer chem- istry and of the electrode morphology on the distribution of the reaction rates. To achieve this objective, electrochemical and spectro-electrochemical methods shall be used.

- Design of spectro-electrochemical cells adapted to study electrochemical interfaces of various complexities by electrochemistry coupled with infrared spectroscopy or laser confocal microscopy; - Study of the pH, cations and ionomer distribution at the electrode- electrolyte inter-face of electrochemical systems of interest for the hydrogen cycle, using electro-chemistry, spectro-electrochemistry and synchrotron-based approaches. - Study of the ionomer (and associated monomers/dimers), of the local pH and of the electrode morphology on the distribution of the reaction rates. - Study of the transport and reaction rate distribution in tri-dimensional electrodes using electrochemical impedance spectroscopy.

The project take place at the institute of chemistry and processes for energy, environment and health (ICPEES), in the electrochemistry and energy conversion team (ECE), under the supervision of Pr. Elena SAVINOVA, Dr. Sergey PRONKIN and Dr. Tristan Asset. This project operates within a major European consortium, including academics partners, research institutes and industrial partners. The project aims to develop a digital platform con-necting multiples research laboratories to increase the efficiency, and ease the development of materials and their integration in systems linked to the hydrogen cycle. The applicant shall work with several of those partners (e.g., Forschungszentrum Jülich GMBH, Paul Scherrer Institute, University of Leiden, etc.) to develop new tools and acquire new knowledge that shall be implemented in said platform.
