Der volle Inhalt der QuelleIn this thesis work, the use of metal-containing nanoparticles such as carbides, oxides and phosphides is explored for colloidal catalysis. In an attempt to build a Frustrated Lewis Pair (FLP)-like catalytic system for H2 activation, the synergy with a molecular Lewis base is assessed. In the bibliographic introduction, the stakes and the challenges of H2 activation in solvent are presented, with an emphasis on the use of non-purely metallic catalysts for the hydrogenation of model compounds. In the first part, early transition metal carbides and hydrides are synthesized via solid-state metathesis. The influence of process parameters is explored to tune the phase speciation in the products. The most promising carbon-supported catalysts, Mo2C/C and W2C/C, are studied for gas phase and liquid phase hydrogenations of olefins. In the second part, cerium and indium oxides are obtained via hydrothermal pathways. The relevance of oxygen defects in CeO2-x is established for H2 gas phase activation and semi-hydrogenation of phenylacetylene in solvent. The last part is dedicated to the non-aqueous syntheses of molybdenum and tungsten oxides, and nickel carbide and phosphides. The syntheses mechanisms are studied by means of NMR for the organic species and XAS and XRD for the nature of the inorganic species. The catalytic activity of the unsupported nanoparticles is finally evaluated for the hydrogenation of nitrobenzene and phenylacetylene in various solvents

Der volle Inhalt der QuelleThe use of nuclear energy obviously raises the question of the presence of radionuclides in the environment. Currently, their mitigation is a major issue associated with nuclear chemistry. This thesis focuses on both the trapping of radionuclides by porous solids called Metal-Organic Frameworks (MOF) and the crystal chemistry of the carboxylate of tetravalent actinides (AnIV). The academic knowledge of the reactivity of carboxylate of AnIV could help the understanding of actinides speciation in environment. We focused on the sequestration of iodine by aluminum based MOF. The functionalization (electron-donor group) of the MOF drastically enhances the iodine capture capacity. The removal of light actinides (Th and U) from aqueous solution was also investigated as well as the stability of (Al)-MOF under γ radiation. More than twenty coordination polymers based on tetravalent actinides have been synthesized and characterized by single crystal X-ray diffraction. The use of controlled hydrolysis promotes the formation of coordination polymers exhibiting polynuclear cluster ([U4], [Th6], [U6] and [U38]). In order to understand the formation of the largest cluster, the ex-situ study of the solvothermale synthesis of compound {U38} has also been investigated

Der volle Inhalt der QuelleThis thesis project was carried out to develop a continuous process for supercritical fluid synthesis of phyllominerals (especially using water as solvent) to fit synthesis time with industrial requirements: about ten seconds only. This innovative route provides synthetic talc with properties such as high mineralogical and chemical purity, large surface area (several hundred m²/g) and hydrophilic nature resulting in the formulation of the first liquid talc mineral (its natural counterpart being hydrophobic). Moreover, supercritical CO2 drying process implementation allows the obtention of very high specific surface area solid material easily rehydratable to prepare stable synthetic talc gel. This process allows synthetic talc functionalization, thus widening the fields of application for this new liquid mineral. Supercritical route appears as the optimal route to develop industrial scale mineral synthesis preparation (phyllosilicates, silicates and others). Environmental impact study of this new process further identifies possible optimization trails to make this route as sustainable as possible

Der volle Inhalt der QuelleThis work, in the area of hydrogen storage, is devoted to the elaboration and characterization of hybrid and inorganic fluorides with open structures. The solvothermal synthesis of hybrid Ti-based fluorides led to seven fluorotitanates with isolated TiF6 octahedra and two oxyfluorotitanates built up from ∞(TiOF4) chains and ∞(Ti5O5F12) layers. Two fluorides with (Cu(pyr)4)•(TiF6)2 trimers and ∞[(Cu(en)2)•(TiF6)] chains were revealed in Ti-Cu systems. The optical gaps of fluorotitanates, estimated from diffuse reflectivity and DFT (density functional theory), demonstrate a F-/OH- substitution. [Hgua]•(Ti5O5F12) (2D) exhibits a photochromic behaviour which is related to the TiIV-TiIII reduction. The synthesis of known microporous fluorides with high surface area was performed. The tuning of the synthesis parameters by using the design of experiments methodology led to nanosized solids with a very high surface area, 345 m2. G-1 for β-AlF3. The measurements of hydrogen adsorption properties at 77K show relatively low capacities for β-MF3 (Fe,Al). At the opposite, amorphous FeF3 presents a significant adsorption capacity which is close to the capacity of the reference materials
