Missions
This project, conducted in collaboration with a major industrial player in the energy transition, will primarily focus on optimizing the methodology for characterizing porous zeolitic materials through the analysis of dynamic breakthrough curves. The main goal is to determine precise qualitative and quantitative mass transport markers by modeling breakthrough curves and fractional adsorbed volumes obtained through equilibrium physisorption to establish unambiguous reference data. The objective is to characterize the efficiency of the pore network in various types of zeolites and study the influence of the mesoporization process. Ultimately, the aim is to achieve a perfect correlation between pore network efficiency (through quantitative descriptors), the catalytic performance of the materials, and the identification of the best catalysts for reactions of interest.
Activités
The first part of the study will involve an in-depth literature review of the best currently available models applicable to breakthrough curve modeling. This initial work should not only isolate the most suitable model for the considered materials but also provide a deep understanding of the implications, applications, and theoretical significance of each parameter. The researcher will then be responsible for a research project aimed at thoroughly understanding the architecture and final pore interconnectivity of modern zeolitic materials using dynamic characterization techniques. These data will need to be correlated with the physicochemical properties of the material and the data obtained through modeling. The rationalization of all these effects will ultimately provide clear and unambiguous references for the expected performance of the materials of interest.
Compétences
The candidate:
• Must hold a Ph.D. in chemistry, chemical engineering, or a closely related field involving materials science, modeling, adsorption, diffusion, and/or mass transfer in confined media.
• Must have relevant experience in dynamic adsorption processes in a broad sense.
• Strong experience in nanoporous material characterization is highly desirable (e.g., IR, XRD, SEM, TEM, gas adsorption, NMR, etc.).
• Experience in the synthesis of zeolitic materials is a significant advantage.
• Should be familiar with adsorption science and experimental techniques for characterizing pore networks (e.g., gas physisorption, DVS, multi-nuclear NMR, dynamic sorption, etc.).
• We seek a highly motivated candidate capable of collaborating within an interdisciplinary team.
• Must be proficient in oral and written communication.
• Fluency in English is essential.
Contexte de travail
The project is a collaboration with a major industrial partner. The work will be carried out at LCS - Laboratoire Catalyse & Spectrochimie (https://www.lcs.ensicaen.fr) located in Caen (Normandy).
The LCS has built its reputation on the preparation of zeolites and related porous materials, operando spectroscopy and catalysis. Combining very strong poles in synthesis of porous materials and spectroscopy. The selected candidate will be attached to UMR6506.
