In recent years ionic liquids became interesting solvents for synthesis not only of organic molecules but also inorganic materials such as metal and metaloxide nanoparticles. One reason for this development is that ionic liquids can dissolve a wide variety of metal precursors due to their intrinsic polarization. In addition their surface properties can influence the growth and shape of the synthesized nanomaterials and their high thermal stability allows syntheses at temperatures up to 250�C including a good energy uptake as a consequence of microwave irradiation. Furthermore the tenside like properties of ionic liquids make ionic liquids ideal materials for the dispersion and stabilization of nanoparticles.In this presentation we will present a new method for the size controlled synthesis of metal nanoparticles and the influence of the anion on the size of the synthesized materials. In addition we will show that nanoparticle powders can easily be deagglomerated and dispersed in various solvents by the addition of ionic liquids as dispersants.
