Abstract

The effect of ionic liquids 1-butyl-3-methylimidazolium tetrafluoroborate, 1-butyl-3-methylimidazolium hydrogen sulfate, and 1-(2-hydroxyethyl)-3-methylimidazoium tetrafluoroborate were studied in the synthesis of silver iodide nanoparticles. Synthesis was performed in Triton X-100 reverse micelles under ambient conditions. Ionic liquids were introduced into the system to determine how they, as solvents, can contribute to forming nanoparticles of uniform size and size distribution. The nanoparticle rate of formation was evaluated by ultraviolet-visible absorption spectroscopy, and the sizes were observed using transmission electron microscopy. The rate of formation was affected by the type of ionic liquid, which is suspected to be a result of the ionic liquid viscosities affecting intermicellar exchange, as well as results of solubility affects on precursor materials in the presence of ionic liquids.
