Oleic acid as the capping agent in the synthesis of noble metal nanoparticles in imidazolium-based ionic liquids

This paper reports the synthesis and automatic separation of solvent dispersible silver and platinum nanoparticles in 1-butyl-3- methylimidazolium bis(triflylmethyl-sulfonyl) imide ([BMIM][Tf2N]) ionic liquid (IL) using oleic acid as the major capping agent.
