The propensity for water electrosorption at gold electrodes. a–d Correlation between the distributions of water density (dashed blue lines, right blue y-axis) and the potential of mean force (PMF) for water (solid red lines, left red y-axis) for room temperature ionic liquids at gold electrodes: in 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([pyr14][TFSI]) at a negative and b positive electrodes, and in 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) near c negative and d positive electrodes. The applied potential between the two electrodes is 4 V, and the PMF curves are obtained by umbrella sampling along the distance from the electrode surface. The electrical double layer potential (ΦEDL) at negative or positive electrode is labeled in each panel
