Context & Job description
Thesis subject: Enhanced carbon dioxide reforming of methane using combined zeolite catalysts
You will join the ID22 team at the ESRF. ID22 is a versatile instrument that can be exploited for a wide range of high-resolution powder diffraction measurements. The PhD project is in relation with the study and efficiency enhancement of the CO2 reforming of CH4 catalytic process (DRM), using in situ high-resolution X-ray powder diffraction. CO2 reforming of CH4 consists in reacting these two main greenhouse gases to produce syngas (H2 and CO). While zeolite-based catalysts are promising candidates, the challenge is to cope with rapid catalyst deactivation due to secondary reactions, inappropriate for industrial applications.
In this project, a series of zeolites with tailored properties will be studied interacting with the relevant gases experimentally and by molecular dynamic simulation, to promote syngas synthesis while minimizing secondary reactions and catalyst deactivation. Structural evolution of the catalyst, adsorbed molecules and interaction molecule-zeolite will be followed in situ at ID22 by high-resolution anomalous diffraction, thus combining spectroscopy and diffraction. Results from both Rietveld refinements and molecular dynamic simulations will be combined in order to evaluate the efficiency of the different materials and to design the best strategy for an industrial use of the DRM process.
Expected profile
Degree allowing enrollment for a PhD (such as MSc, Master 2 de Recherche, Laurea or equivalent) in chemistry, physics, materials science or closely related science Interest in X-ray powder diffraction techniques and Rietveld refinement is desirable Knowledge of basic programming (python) would be an asset English proficiency (working language at the ESRF)
Working conditions
The salary will be calculated on the basis of relevant qualifications and professional experience.
