Abstract

original image

Specific adsorption: Molecular dynamics simulations of the imidazolium-based ionic liquid/graphite electrode interface illustrate the effects of specific adsorption of the imidazolium cation on both differential capacitance and electric double-layer structure due to the π-stacking interaction between the imidazolium cation and the graphite surface.
