Gold Particle Synthesis via Reduction of Gold Salt in the Ionic Liquid 1-Butyl-3-Methylimidazolium Tetrafluoroborate Aqueous Solution
Abstract:The formation of gold particles via reduction of HAuCl4·4H2O by ascorbic acid in the presence of ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate and sodium alginate has been studied. The shape of the synthesized particles could be tuned by controlling the reaction conditions. Specifically, the flowerlike gold particles can be synthesized by the present synthetic route. It demonstrates that both the ionic liquid and the sodium alginate play an important role for the formation of the flowerlike particles. The synthesized flowerlike particles show enhanced electroactivity for H2O2.
