Ionic liquids under complex confinement. (a) The simulation cell consists of a [BMIM][PF₆] ionic liquid and two porous electrodes (CDC-1200) held at a constant electrical potential.²⁶¹ Reproduced with permission from ref (261).

(b) Adsorption of ions in a nanoporous carbon electrode at zero potential difference, and the representative configurations of ions for the four adsorption modes: edge, plane, hollow, and pocket. The gray rods and gray spheres are the C–C bonds, and carbon atoms, respectively. The red color shows [BMIM]⁺ cations, the green colors denote [PF₆]^– anions, and the blue color shows ACN molecules, respectively.⁵¹ Reproduced with permission from ref (51).
