摘要: Abstract Highly stable and hydrophilic ionic liquid-capped gold nanoparticles were synthesized by in situ reduction of HAuCl 4 with NaBH an aqueous medium. Two kinds liquids (ILs) used this work: namely, 1-dodecyl-3-methylimidazolium chloride [C 12 mim][Cl] a geminal-IL (GIL), 1,4-bis(methylimidazolium-1yl)dodecane bromide, two head groups. Prepared characterized UV–vis spectra, transmission electron microscopy (TEM), dynamic light scattering (DLS) analysis FTIR spectroscopy. To the best our knowledge is first report on using these types ILs nanoparticle synthesis. The results showed synthesis low polydispersed sizes about 10 nm. IL ([C mim][Cl]) capped for at least 8 months.
