Développement de MOFs fonctionnels sur support solide : application à la photochimie.

Abstract : This work is focused on the development of a functionalization method of TCO transparent conductive surfaces (Transparent Conductive Oxide) by hybrid multifunctional materials, Metal-Organic Frameworks (MOFs). Different properties are provided within the MOF by adding different photosensitive and catalytic units. The development of such materials is in its infancy and they have been mainly developed as crystalline powder. However the development of these MOFs onto a solid support is challenging but also essential toward obtaining a technologically advanced device.This project is focused on the growth controlled of MOFs crystals onto TCO support. From a Zirconium material, it was possible to obtain multifunctional systems by changing components directly during the synthesis or by post synthesis modifications. It has been possible to control the growth of materials on the support by direct in situ solvothermal synthesis and to obtain a monodisperse layer of crystals well anchored to the TCO supports. Photodegradation of methylene blue (organic pollutant) has been performed to validate their photoreactivity.The methodology developed with the Zirconium based MOF has been implemented successfully in a similar compound to include higher photosensitizer components and with titanium-based MOFs. It shows the portability of the strategy towards other types of MOFs. They were used in CO2 photo-reduction (in collaboration of the College de France) where selectively of formate production was observed.
