Double layer of Au(100)/ionic liquid interface and its stability in imidazolium-based ionic liquids

Angew Chem Int Ed Engl. 2009;48(28):5148-51. doi: 10.1002/anie.200900300.

Abstract

Ring any bells? The differential capacitance curve of Au(100) in neat [BMI]BF(4) (BMI = 1-butyl-3-methylimidazolium) ionic liquid has a bell-shaped feature (see picture). The adsorption of BMI(+) shows a disorder-order transition and depends on the structure of the surface. Ordered adsorption in a micelle-like structure stabilizes the underlying Au surface.
