Topic: Finding efficient ways to store and deliver electrical energy is urgently needed for the large-scale development of renewable energy sources. The use of pseudocapacitive materials, such as 2D transition metal carbides and nitrides, so-called MXenes, is an extremely promising solution to achieve electrochemical energy storage with high power and energy densities. Nevertheless, local electrochemical processes occurring at the MXene-electrolyte interface are currently largely unexplored. In this presentation, I will show how synchrotron-based scanning X-ray microscopy can allow chemical imaging of electrochemical processes on individual MXene flakes.
CV: Tristan Petit received a PhD in Physics from ENS Cachan, France in 2013 working on the surface chemistry of nanodiamonds at the CEA Saclay in France. Before that, he followed a double master degree program from ISAE-Supaéro, France and ETH Zürich, Switzerland and graduated in 2010. He arrived in Berlin in 2013 with a Humboldt Postdoctoral fellowship at HZB and further received a Freigeist Fellowship from the Volkswagen Foundation in 2015 and an ERC Starting Grant in 2020. His research focuses on in situ/operando spectroscopy of carbon nanomaterials and MXenes for energy conversion and storage applications.
Following the lecture, there will be a get-together where participants can exchange ideas with each other over pizza and drinks in the Remise and the garden of the Magnus-Haus.
The event is sponsored by the Wilhelm and Else Heraeus Foundation.
