Welcome to Prof. Eddaoudi’s
RESEARCH GROUP!
The Functional Materials Design, Discovery & Development research group, headed by Prof. Mohamed Eddaoudi, is mainly focusing on the development of new strategies to design and synthesize new functional solid-state materials for different applications such as gas storage/separation, catalysis. In order to address challenging societal issues such as carbon capture, FMD3 has set up strategies for the construction of nanosized, thin films and membranes based MOFs.

The search for effective carbon-capture materials has permitted the disclosure and institution of nanoporous fluorinated metal–organic frameworks (MOFs) with a contracted pore system as benchmark CO2-selective adsorbents. Namely, the SIFSIX-3-M (M = Zn, Cu, and Ni) MOF adsorbents, encompassing a periodic arrangement of fluorine moieties in a confined one-dimensional channels, exhibit a remarkable CO2 adsorption-based selectivity over CH4 and H2 in various industrially related gas mixtures. Here, we report the successful transplantation/integration of this distinctive CO2 selectivity, distinguishing this class of nanoporous MOF adsorbents to pure MOF membranes for carbon capture. Markedly, the liquid-phase epitaxy (LPE) growth approach permitted, for the first time, the building of continuous, homogeneous, and defect-free MOF membranes based on the SIFSIX-3-M platform, MSiF6(Pyz)2 with M = Ni or Cu, on a porous alumina substrate. Single and mixed-gas permeation tests revealed that the resulting nanoporous MOF membrane is a CO2-selective membrane, exhibiting the foreseen favorable CO2-selectivity toward carbon dioxide over H2, and CH4, governed by the CO2-selective adsorption in the functional and contracted channels of the SIFSIX-3-M.
