Dataset of the electrochemical potential windows for the Au(hkl)|ionic liquid interfaces defined by the cut-off current densities

This data article describes the linear sweep voltammetry (LSV) profiles of five ionic liquids (ILs) at the low-index (hkl) (hkl = 111, 100, and 110) planes of Au. The LSV profiles were recorded at 25 ± 1°C for the Au(hkl)|IL interfaces maintained in a hanging meniscus configuration in an inert Ar at...
