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...

| description | 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 atmosphere (with H2O and O2 concentrations being lower than 5 ppm). The width of the electrical double-layer regions (Edl) and the electrochemical potential windows (Epw) of the ILs were evaluated based on the cut-off current densities (jcut-off): ±5, ±10, and ±20 µA cm–2 for Edl and ±0.1, ±0.5, and ±1.0 mA cm–2 for Epw. The potential values were calibrated to the redox potential of ferrocene/ferrocenium in each IL. A detailed discussion on the electrochemical behaviors of the ILs on Au(hkl) is provided in the related article “Voltammetric Investigation of Anodic and Cathodic Processes at Au(hkl)|Ionic Liquid Interfaces”, published in the Journal of Electroanalytical Chemistry (Ueda and Yoshimoto, 2021). |
