Thermochemical conversion of biomass produces tar, as an inevitable byproduct, which was a potentially precursor for carbon material preparation. This study provided an approach of preparation of tar-based Fenton-like catalytic nanoparticles from waste biomass tar via green solvent-free approach. The monoand bimetallic nanocatalysts were synthesize...

L'imagerie de photoluminescence synchrotron apparaît comme uneméthode particulièrement prometteuse pour l’étude de matériaux hétérogènesmêlant composés minéraux et organiques, comme ceux des sciences des matériaux anciens.Au cours de ce travail de thèse, nous avons développé le dispositif de microscopie de photoluminescence existant de la ligne DIS...
A new kind of electrolyte composed of molten fluorides has been evaluated in order to perform a feasibility study of the direct electroreduction reaction. The direct reduction of SnO2 and Fe3O4 was realised in LiF-NaF at 750°C and in LiF-CaF2 at 850°C for TiO2 and TiO. The electrochemical behaviour of these oxides was studied by linear sweep voltam...
