Texte intégralThe depletion of fossil resources and increasing environmental concerns encourage the production of sustainable chemicals and fuels from biomass resources and CO2. The fundamental target of this research project deals with the design of a novel single atom micellar catalyst system. Catalysts are conventionally classified into homogeneous and heterogeneous. Homogeneous catalysts offer high efficiency, related to maximal metal utilization and highly accessible active sites, and high selectivity, due to the similar active site's structure. However, homogeneous catalysts often suffer from low stability and poor recyclability. On the contrary, heterogeneous catalysts exhibit excellent stability and recyclability, yet their active metal utilization and selectivities are typically low. Single-atom catalysts (SACs) are an emerging family of materials that combine the best advantages of homogeneous and heterogeneous catalysts. SACs display approximately 100% atomic utilization, relatively high stability, and easy separation from the reaction media. However, there are several drawbacks associated with the use/synthesis of single-atom catalysts: most synthetic procedures for SACs require the use of expensive throw-away ligands and highly specialized equipment and techniques that hinder their scale-up production and applicability. A solid micellar SAC has been developed in the framework of this project by the incorporation of metal atoms into the walls of MCM-41, stabilized by a Cetyltrimethylammonium (CTA+) surfactant. The method is very simple and cheap to synthesize since it does not require the addition of expensive ligands or inert atmosphere techniques

Texte intégralBecause of their high chemical and thermal stabilities, metal fluorides have found to be advantageous over metal oxides in such cases where reactions involving generation of corrosive acids like HCl and HF are concerned. The Sol-gel method is known for the synthesis of materials with considerably different properties to those prepared by classical routes. In this work, sol-gel route has been employed for the synthesis of binary fluorides (AlF3, MgF2, CaF2, CuF2 and FeF3), hydroxyfluorides [AlF3-x(OH)x, MgF2-x(OH)x] complex fluorides (KMgF3, K3AlF6), metal fluoride supported nanoscopic noble metals (Pd, Pt) and host-guest fluoride systems (CuF2/AlF3, FeF3/AlF3). Besides the successful synthesis of metal fluorides described above, the present thesis deals with investigation of their bulk and surface properties using various analytical and spectroscopic methods (XRD, BET, NH3-TPD FTIR-pyridine adsorption, XPS, microscopic studies) as well as with their catalytic properties for the reactions of academic and industrial interest. Metal fluorides prepared via sol-gel method have shown to possess extraordinary surface properties in terms of surface area, particle size, porosity, Lewis acidity and distortion in their structures as compared to those of classical methods like aqueous synthesis or impregnations. A homogeneous dispersion of Pd nanoparticles supported on high surface area metal fluoride prepared by this method was confirmed by XRD, XPS and TEM imaging. Catalytic properties of these materials have been investigated for dehydrofluorination of hydrofluorocarbons, isomerization of citronellal, hydrodehalogenation of chlorodifluoromethane, Suzuki cross coupling and oxidative fluorination of benzene.

Texte intégralFischer–Tropsch (FT) synthesis converts syngas into liquid hydrocarbons over cobalt catalyst for new ultraclean alternative fuels. The syngas can be produced from both fossil and renewable resources. The catalysts for FT synthesis are currently prepared by chemical ways like impregnation etc. All these routes involve toxic solvents and high temperature retreatment. Because of lower cost, reduced energy requirements and environmental pollution, the mechano-chemistry has a number of advantages for the synthesis of heterogeneous catalysis compared to conventional techniques. In this study, the mechano-chemical method was used to prepare alumina supported cobalt catalysts for FT synthesis. Differently to the conventional catalyst preparation, the deposition of active phase did not involve any solvent in the proposed method. The goal of this work is to obtain efficient FT catalysts and to simplify catalyst synthesis by reducing the number of preparation steps. The project involves innovative method of synthesis of catalysts in three different mechanical working processes in dry context. The process of mechano-chemistry to synthesize the catalyst for FT reaction was developed. The operating conditions for the control of the coating technique were identified through optimal conditions study by statistical analysis. Moreover, characterizations were studied to understand the basic mechanisms behind deposition of particles on the interface. Catalytic performance tests were estimated in a mili-fixed bed reactor; Optimization algorithm of parameters in a mechanical process was carried out via deriving target formula about energy and material size
