The development of solar-to-fuel conversion systems is a crucial step to the advent of societies with low consumptions of fossil and nuclear energies. The design of these artificial photosynthetic systems inspires largely from natural processes, which can convert sunlight and atmospheric carbon dioxide into complex organic molecules.
In this presentation, we will present our work concerning the development and use of analytical methods based on X-ray spectroscopies to understand the structure of natural and artificial photosynthetic systems. In a first part, we will describe how these techniques can be used to determine the local and electronic structure of biomimetic complexes, which model the active site of Photosystem II. We will show in a second part how X-ray techniques can be used to study, under operating conditions, fuel-producing electrocatalysts. Finally, we will present our current work, which uses microfluidic tools to develop novel electrochemical energy conversion systems.
