- Metal nanoparticles were successfully synthesized from the self-regulated reduction of hydroxylated
ionic liquids in aqueous phase without additives. A new water-phase synthesis of gold and palladium
nanoparticles using N-(2-hydroxyethyl)-N-methylmorpholinium tetrafluoroborate is described. Transmission
electron microscopy was performed to characterize the metal nanoparticles. The average
sizes of the gold and palladium nanoparticles were 4.3 nm and 3.2 nm, respectively. Hydroxylated
ionic liquids served as both reductants and protective agents, significantly simplifying the preparation
of nanoparticles. The produced particles were highly crystalline in structure with a face-centered
cubic (fcc) lattice. Finally, we showed preliminary results that suggest different hydroxylated ionic
liquids can also be used to prepare various metal nanoparticles.
