PhD student (October 2024-October 2027), under the supervision of Olivier Guaitella.

My research project, titled "Plasma Regeneration of Adsorbents of Co₂ for direcT aIr CapturE (PRACTICE)", focuses on the study of plasma-surface interactions for the development of innovative Carbon Capture and Utilization strategies. Using low temperature plasmas, my goal is to regenerate efficiently CO₂-loaded adsorbents and convert the extracted CO₂ into added-value chemicals (CO₂-neutral fuels).

My experiments include the characterization of solid adsorbents of CO₂ (mostly alkaline earth metal oxides such as MgO or CaO) exposed to various plasma sources (DC glow, RF, pulsed discharges, DBDs,...) with multiple interface geometries (pelletized material, packed bed, fluidized bed,...). Through the development of several in-situ, time resolved diagnostics of both the plasma and the solid phases, my work aims at a better understanding of the fundamental mechanisms ruling the adsorption, desorption and conversion of CO₂ under plasma exposure. 

This work is carried out in close collaboration with Disha Bhattacharjee, who is synthesing innovative materials for CO₂ capture at the Laboratoire de Chimie Moléculaire (LCM, IP-Paris), and is financially supported by the Polytechnique Foundation through the "Thèses à Objectifs de Développement Durable" program, which aims at promoting promising PhD projects centred on sustainable applications.
