“…17,18 To prevent aggregation, NPs must be stabilized by the use of capping agents such as (water-soluble) polymers, quaternary ammonium salts, surfactants, ligands or polyoxoanions, providing electronic and/or steric protection. 19,20 In this context, ionic liquids (ILs), dened as low temperature molten salts, have emerged as one of the most important and the most investigated media for the synthesis of metal NPs. [21][22][23][24] Moreover, an advantage of using ILs is that stabilizing additives such as ligands, polymers and supports are not required.…”
