The change of the potential of zero charge (pzc) of a single layer graphene (SLG) electrode in contact with EMI,TFSI ionic‐liquid‐based electrolyte is reported by Yanwu Zhu, Patrice Simon, and co‐workers in their Research Article on page 13317. The strong interactions between the SLG surface and the EMI + cation (red) in neat ionic liquid are weakened in the presence of acetonitrile solvent molecules (yellow), leading to an increase in the charge carrier density at the electrolyte/SLG interface and a positive shift of the pzc.
