Materials processing in ionic liquids (MAPIL).

Ionic liquids are molten organic salts with a melting point below 100 ° C. They have interesting properties such as a negligible vapor pressure, high thermal and electrochemical stability, good electrical conductivity and temperature-dependent miscibility with organic solvents. The objective of this project is the application of ionic liquids for the manufacture and processing of materials. In particular the emphasis is on the synthesis and use of ionic liquids for electrodeposition of reactive materials and catalysts. New ionic liquids that are suitable for the electrodeposition of metals that cannot be deposited from aqueous electrolytes (e.g. aluminum or tungsten) and for the electrodeposition of metals on substrates passivated in aqueous environment (e.g. deposition of platinum on titanium mesh ) are being developed. Porous, skeleton-like heterogeneous catalysts are produced by electrodeposition on metal carriers and their catalytic activity will be tested. The negligible vapor pressure of ionic liquids allows electrodeposition under vacuum conditions. Therefore the contamination of the electrolyte bath with water and oxygen can be avoided. The development of new ionic liquids takes into account the requirements of sustainable development so that the focus is on ionic liquids containing non-fluorinated anions.
