1-year post-doc in Lille (France)

Dear all,

We are looking for a motivated post-doctoral researcher in Centrale Lille (France), for 1 year. The candidate will be able to rely on the expertise of the supervisors concerning the synthesis of MOFs and their characterization, in particular using very high field spectrometers from the University of Lille available (800 MHz, 900 MHz and 1.2 GHz).

Context of the project: The vulnerability of current natural and human systems requires the deployment or use of new sources of energy. In this context, hydrogen gives rise to much hope. It is an attractive fuel due to its easy production without CO2 emissions. But, large-scale H2 production by water electrolysis generates by-products, such as CH4, O2 or N2. Therefore, there is a need to develop energy- and cost-efficient techniques to separate H2 from unwanted molecules. Various materials, including organic polymers, Pd-based metallic membranes, zeolites, or carbon molecular sieves, have been tested for H2 separation. Recently, metal-organic frameworks (MOFs) have emerged as a promising novel class of molecular sieve for H2 separation owing to their tunable pore size and pore surface functionality. But some questions remain unsettled. How does the structure of MOFs affect the adsorption and diffusion of H2 and CH4 in MOFs? What is the permeability of these materials towards these gases and therefore their selectivity for their separation? Even though the insertion of H2 in MOF has already been investigated in the literature through X-ray diffraction, neutron diffraction, adsorption isotherms or IR spectroscopy, the dynamics of H2 and the host-guest interactions are difficult to retrieve by those methods. Thus, the rational optimization of H2 separation using MOF requires atomic-level characterization of these materials. Nuclear Magnetic Resonance (NMR) is a method of choice since it is sensitive to the local environment, and provides, with the help of ab initio calculations and simulations, precious information regarding the dynamics components of guest molecules and their interaction with their host.
The candidate must have a PhD with a background in either MOF synthesis or NMR spectroscopy. It should show initiative, should have the ability to work independently and have good communication skills.
