Project objective

Noble metals nanoparticles will serve as catalysts in supercritical fluids-ionic liquids biphasic systems. Hydrogenations, oxidations and C-C bond formations processes are targeted. Higher activities together with good selectivities of the catalysts are aimed.In-situ synthesis on stable nanoparticle is targeted, using as precursors simple salts or organometallic compounds. The simplicity and reproducibility of preparation will be addressed, and hydrogen will be preferred as reductive agent. The effect o f ionic liquids structure over the nanoparticle stability and catalytic properties will be established, and the proper ionic liquids will be chose for a longer life the nanoparticles catalytic system.Nanoparticles will be characterized by established techniques (electron microscopy) and size and shape effects on activity and selectivity will be assessed. Supercritical CO2 is considered a solvent with tunable properties, especially around critical point. This property offers further advantages, offering a way for controlling the solubility of reaction product, and allowing a neat separation.Due to the benign character of carbon dioxide, this process may be able to offer a cleaner alternative to classical processes employing molecular solvents. The biphasic system allows a facile separation of the products, stops the leaching of precious metals, and allows a simple and efficient catalyst recycling.
