Ibrahim, Mahmoud. « Rhodium based mono-and bi-metallic nanoparticles : synthesis, characterization and application in catalysis ». Thesis, Toulouse 3, 2016. http://www.theses.fr/2016TOU30063/document.
Texte intégralIn this thesis, synthesis, characterization and catalytic applications of mono- and bi-metallic rhodium-based nanoparticles are reported. Rhodium has been chosen as a primary metal given its high interest in catalysis, mainly in hydrogenation and hydroformylation reactions. The synthesis of mono-metallic rhodium nanoparticles (NPs) is the core of this work. It was performed by decomposition of the organometallic complex [Rh(C3H5)3] in solution under dihydrogen pressure and in the presence of different stabilizers including ligands and polymers to control the growth of the particles. Selected nanoparticles were deposited on the surface of amino-functionalized magnetic silica as a support for recovery and recycling concerns in catalysis. Diverse bi-metallic nanoparticles have been also prepared in one-pot conditions by co-decomposition of the [Rh(C3H5)3] with other organometallic precursors including [Ni(cod)2], [Ru(cod)(cot)], [Pt(nor)3] and [Pd(dba)2]2. Tuning of the metal ratios between [Rh] and the second metal [M], or of the nature and the amount of the stabilizer used for the synthesis allowed to obtain nanoparticles of different sizes and chemical compositions. The characterization of the obtained nanoparticles was performed by using a combination of state-of-art techniques (TEM, HRTEM, STEM-EDX, ICP, WAXS, EXAFS, Xanes, XPS, NMR...). Surface studies were carried out in some cases, by adsorbing CO on the surface of the particles which was followed by spectroscopic techniques (FT-IR, NMR) to probe their surface state. Some of these nanoparticles were investigated in catalytic reactions, mainly hydrogenation with Rh NPs and hydrogenolysis for RhNiOx NPs. Both colloidal and supported catalytic studies were carried out in the case of hydrogenation catalysis. The originality of this work lies in the development of simple synthesis tools inspired from organometallic chemistry to get well-controlled rhodium-based nanoparticles in terms of size, size distribution, composition and surface state, all these parameters being important whatever the target application. The interest of the obtained nanoparticles in catalysis has been also evidenced in different reactions. This PhD work may open new opportunities of research both in nanochemistry and catalysis
Ayvali, Tugçe. « Rhenium based mono- and bi-metallic nanoparticles : synthesis, characterization and application in catalysis ». Thesis, Toulouse 3, 2015. http://www.theses.fr/2015TOU30269/document.
Texte intégralIn this PhD thesis, the synthesis, characterization and preliminary catalytic application of rhenium based mono- and bi-metallic nanoparticles are reported. Rhenium has been chosen as a primary metal given the knowledge of its positive contribution in terms of catalytic activity and selectivity in the hydrogenation of difficult functional groups. Mono-metallic rhenium nanoparticles were prepared by decomposition of [Re2(C3H5)4]. Rhenium-based bimetallic nanoparticles were synthesized by co-decompositions or two-step decomposition of two different rhenium complexes, namely [Re2(CO)10] and [Re2(C3H5)4], with other organometallic complexes such as [Ru(COD)(COT)], [Ru(Me-Allyl)2(COD)], [Pt(CH3)2(COD)] and [Pt(C7H10)3]. By tuning the nature of organometallic complexes and the reaction conditions, rhenium-based bimetallic nanoparticles displaying different morphologies could be quantitatively prepared. The synthesis was carried out in solution under mild pressure of dihydrogen (3 bar) and in the presence of either a polymer (polyvinylpyrolidone) or a weakly coordinating ligand (hexadecylamine) as stabilizing agents. The precise characterization of the so-obtained nanoparticles was performed by using a combination of state-of-the art techniques (WAXS, EXAFS, TEM, HRTEM, STEM-EDX, STEM-HAADF, EA). Surface reactivity studies (norbornene hydrogenation, oxidation and CO adsorption reactions) were also carried out and followed by spectroscopic techniques (NMR, FT-IR) to determine their surface state and apprehend better their interest in catalysis. By this way, useful information could be obtained on their surface chemistry, as following: 1) Hydrides are present on the metallic surface and are very strongly coordinated to rhenium in agreement with rhenium molecular chemistry; 2) CO can substitute hydrides and is also strongly coordinated to the surface of Re but can react further to be substituted, oxidized or dissociated, where the latter is easier on alloy type Re-based bimetallic nanoparticles. 3) Oxidation of pure rhenium and alloy bimetallic ruthenium-rhenium nanoparticles display a zero state core and an oxide shell while core-shell type bimetallic nanoparticles result in amorphous structure. The originality of this work lies on the development of a systematic approach for the preparation of rhenium-based nanoparticles for the first time in the team and in the literature, by applying the organometallic approach largely experienced in the group for other metal systems. This method is well-known as an efficient way to obtain well-controlled nanostructures with clean surfaces, important mainly in catalysis
