Syntheses and modifications of MOFs for applications in catalysis and gas storage (Doctoral thesis)
Metal-organic frameworks, commonly abbreviated as "MOF", are porous solids formed by the three-dimensional assembly of metal centers, or clusters, and bridging organic ligands. These relatively new compounds are currently of increasing interest in the scientific community. Their porosity as well as the presence of metal sites and organic ligands which can carry multiple functions make them ideal materials for a very broad scope of applications, in particular in gas storage / separation, catalysis, capture of pollutants, detection of toxic molecules, etc.
In our laboratory, we focus on the development of MOFs with a particular stability, both from a thermal point of view and with respect to solvents or to acidic and / or basic conditions. We are developing new synthetic methods to obtain these materials, in particular by respecting the principles of "Green Chemistry". The compounds thus obtained are modified in many ways, either by metal exchange and / or ligands or by functionalization of the metal sites with additional ligands. This makes it possible to obtain materials with new or improved properties compared to the starting MOF. These are mainly studied in applications in catalysis, in particular for the recovery of CO2 into molecules directly usable in industry, and in gas adsorption.
The characterization methods used for this project are very diverse and cover thermogravimetric (TGA, DSC), spectroscopic (FTIR, UV-vis, liquid and solid NMR, Raman, XPS, EXAFS, etc.), crystallographic (PXRD and single crystal diffraction, ex-situ or in-situ), chromatographic (GC, HPLC), microscopic (optical and electronic microscopy) as well as methods of study of gas adsorption at high and low pressure (BET, BJH, PCT). More specialized methods are also used for the characterization of MOFs as catalysts. The synthetic methods used bring together the conventional synthetic routes of organic and inorganic chemistry (including mechanochemistry), as well as methods requiring manipulation under controlled atmosphere and / or under pressure.
This multidisciplinary project is carried out in co-promotion with professors Sophie Hermans and Yaroslav Filinchuk (MOST, IMCN). The project is funded by two FRIA grants for a total duration of 4 years.
