The electrochemical behavior and specific adsorption of an ionic liquid, 1-butyl-3-methylimidazolium iodide, on a Au(111) electrode surface were investigated via voltammetric analyses, X-ray photoelectron spectroscopy (XPS), and scanning tunneling microscopy (STM). The electrochemical potential window and the reductive desorption of I adatoms were evaluated using voltammetric techniques. The XPS and STM results supported the specific adsorption of I adatoms on Au(111). Furthermore, high-resolution STM images revealed the formation of characteristic nanostructured rings consisting of imidazolium cations on I adatoms for the first time.
