제목 Synthesis gold nanoparticles in ionic liquid using sodium oleate as reducing agent.
초록 Gold nanoparticles was found to be synthesized by reducing gold (III) chloride solution using sodium oleate as reducing agent in the presence of ionic liquid as caping agent. In this study, two methods that were used are High temperature method and Room temperature method with Ultrasonic assistance. The produced gold nanoparticles and nano-seeds were observed by Scaning Electron Microscope (SEM) image and Transmission Electron Microscopy (TEM) image. The comparison between the methods and ionic liquid was realized by Ultraviolet-visible Spectroscopy (UV-vis). The result has shown that gold nano-seed can be produced in any condition of the reaction with suitable ratio of reactant, and the shape of bigger particles that grow from these seed is depended on the synthetic method and the type of ionic liquid which were used.
