Electrosorption of water from humid ionic liquids on electrodes. a, b show water adsorption from the humid 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([pyr14][TFSI]) and 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) with respect to the electrical double layer potential (ΦEDL), respectively; results for gold electrode are shown by blue triangles and for carbon electrode by red circles. The relative enrichment or depletion of water molecules in the first interfacial layer is depicted by the ratio of averaged number density of water in this layer to that of water in the bulk region (\({\bar{\mathrm \rho }}_{\mathrm{n}}^{{\mathrm{ad}}}/{\bar{\mathrm \rho }}_{\mathrm{n}}^{{\mathrm{bulk}}}\)). Enrichment (depletion) zone corresponds to a higher (lower) water density than in the bulk. The error bars are due to the standard deviation of the results based on three independent simulation cases. Source data are provided as a Source Data file
