Ce travail est divisé en deux parties. La première partie commence par une recherche bibliographique sur les mécanismes de formation de γ-Al2O3 poreuse par précipitation sol-gel en voie aqueuse. Le comportement de catalyseurs Ni-Me (Me = Mo, Mn, Fe, Co, Cu) supportés sur γ-Al2O3 est ensuite étudié. Il est montré que l’ajout de platine permet d’augmenter la réductibilité des oxydes métalliques formés lors de la synthèse de ces catalyseurs et de diminuer la taille des nanoparticules métalliques obtenues après réduction. La fonctionnalisation du support par un groupement ligand permet de favoriser initialement la formation d’aluminates (spinelles) mais augmente leur réductibilité. La structuration du support par l’utilisation d’un surfactant (acide stéarique) n’a pas réussi mais a néanmoins permis d’augmenter la surface spécifique et de réduire le frittage des nanoparticules métalliques supportées par augmentation de la microporosité. La deuxième partie consiste en des essais de dépôt d’un catalyseur Ni-Al2O3 sous forme de couche sur des monolithes par trempage. De nombreux défauts sont observés (zones sans couche, fracturation, agrégats) qui sont partiellement résolus par des modifications appropriés de la procédure expérimentale et des solutions de dépôt.

This work considers the behaviour of two nickel-base alloys under thermo-mechanical fatigue loading with varying phase angles between mechanical strain and temperature. The investigations focus on the characterisation of microstructures and damage mechanisms as a function of the phase angle. Based on the results, a life prediction model is proposed.

This book shows how severe plastic deformation techniques could be used to enhance the hydrogen storage properties of metal hybrides. The mechanochemical techniques of ball-milling (BM), Cold Rolling (CR), Equal Chanel Angular Pressing (ECAP) and High Pressure Torsion (HPT) are covered. Each technique is described and critically assessed with respect to its usefulness to process metal hybrides at an industrial scale.

This thesis focuses on the controlled synthesis of Pt–Ni bimetallic nanoparticles and the study of their catalytic properties. It discusses in detail the nucleation mechanism and the growth process of bimetallic systems, which is vital for a deeper understanding of the design of bimetallic catalysts. The author presents four pioneering studies: (1) syntheses of water-soluble octahedral, truncated octahedral, and cubic Pt–Ni nanocrystals and the study of their structure-activity relationship in model hydrogenation reactions; (2) a strategy for designing a concave Pt–Ni alloy using controllable chemical etching; (3) defect-dominated shape recovery of nanocrystals, which is a new synthesis strategy for trimetallic catalysts; (4) a sophisticated construction of Au islands on Pt−Ni, which is an ideal trimetallic nanoframe catalyst. This thesis inspires researchers working in materials, catalysis as well as other interdisciplinary areas. .
