Повний текст джерелаAmong several nanocatalysts, those based on noble metal NPs deserve particular attention because of their electronic, chemical and even optical properties (in the case of plasmonic-enhanced transformations). Platinum or palladium are well known for their remarkable catalytic properties, but they are expensive and their resources are limited. In addition, single component nanocatalysts can only lead to a limited range of chemical reactions. Thus, our strategy was to develop bimetallic nanocatalysts composed of two metal elements that can exhibit synergistic effects between their physicochemical properties and enhanced catalytic activity. We have thus designed bimetallic nanocatalysts of the core-shell type composed of a silver core and a platinum shell. The interest is to combine the high and efficient catalytic activities of the platinum shell surface with the highly energetic silver core capable of enhancing the activities of the shell through its plasmonic properties. In addition, these bimetallic NPs often exhibit superior catalytic activity due to the modification of the Pt-Pt atomic bonding distance (i.e. the strain effect). In this thesis work, Ag@Pt NPs have been synthesized via a two-step process using chemically synthesized spherical Ag NPs as seeds on the one hand and platinum complexes with oleylamine on the other hand which are then reduced on the surface of the seeds at a controlled temperature. Different Ag seed sizes from 8 to 14 nm with a very low size distribution (<10%) have been obtained by adjusting the reaction time, temperature ramp, Ag precursor concentration and final temperature during the synthesis. The control of the shell thicknesses (from 1 to 6 atomic layers) has been possible by adjusting the ratio of platinum precursor to silver seed concentrations. The catalytic activity of the core-shell Ag@Pt NPs was tested by a model reaction of reduction of 4-nitrophenol to 4-aminophenol by NaBH4 in aqueous phase. We have observed that the thickness of the Pt shell and the size of the Ag core influence the catalytic properties and led increased catalytic activity compared to pure silver or platinum. This was attributed to synergistic effects. Furthermore, we have observed an enhancement of the catalytic activity of Ag and Ag@Pt NPs under light irradiation. This is correlated to the generation of hot electrons in the Ag core. Finally, in order to develop a supported nanocatalysis platform, 3D self-assemblies also called supercrystals composed of Ag@Pt nanoparticles have been spontaneously obtained after deposition on a solid substrate due to their narrow size distribution and homogeneous shape. The catalytic activity of these supercrystals for the hydrogen evolution reaction (HER) has been studied by following in situ by optical microscopy the production of H2 gas nanobubbles. Three distinct behaviors in photo-catalytic activity (activity, intermittent activity and non-activity) have been observed on the supercrystals in the same region of interest. In addition, 50% of the assemblies were determined to be active for HER which was shown to be accompanied by oxidative corrosion of silver

Повний текст джерелаThe main goal of this study is to better understand physico-chemical phenomena during SHS reactions. The quench method enabled us to characterize the product microstructure during transitional steps of the TiC synthesis. First seeds of carbide nucleate on C particles from a titanium liquid phase. Thanks to WDS, we showed that TiC grain composition and size continuously increases until it reaches the stoichiometry and its equilibrium size. The grain growth occurs also with other phenomena which lead to the broadening of the grain size distribution but also to a lognormal type distribution. Infrared thermography enabled us to show that the final grain size is controlled by convolution of temperature and time. Thus, the stabilization of nano-TiC can be achieved by increasing the number of nucleation sites and by decreasing the combustion temperature. We showed the ability to stabilize grains of nano-TiC by adding nanostructured diluents to mechanically activated reactant mixtures

Повний текст джерелаSoot particles emitted during fuel combustion have an important impact on global warming and health. Therefore, the improvement of the knowledge on soot particle formation mechanisms in flames shows an important environmental interest. However, this mechanism is not fully understood. Indeed, the nucleation step, forming primary particles (nuclei) from gaseous PAHs (Polycyclic Aromatic Hydrocarbons), is still speculative and needs accurate experimental data to be fully understood. In this work, two experimental techniques based on laser diagnostics have been implemented, the Jet-Cooled Laser Induced Fluorescence (JCLIF) and the Laser Induced Incandescence (LII), respectively for the measurement of PAHs (naphthalene, pyrene and fluoranthene) and soot particles formed in low-pressure CH4/O2/N2 flames and atmospheric pressure C2H4/air flames. These results offer an original experimental database for the improvement of the understanding of the main chemical pathways leading to soot particle formation. Besides, we also highlight the possibility of generating nucleation flames, i.e flames in which soot particles are essentially formed by nucleation, without growth by soot surface processes. In this thesis, we show that these specific flame conditions could be a unique test case, very well suited for the understanding of the soot nucleation process
