I. Materials Gold (Au) voltammetry electrodes (3.0 mm diameter, 99.95%) were purchased from Prosense. Gold wire (0.25 mm diameter, 99.99 %), Zn wire (1.0 mm diameter, 99.99 %), Ni wire (0.5 mm diameter, 99.99 %), Fe wire (1.0 mm diameter, 99.99 %), Ag wire (0.25 mm diameter, 99.99 %), and Cu foil (thickness 0.25 mm, 99.98 %) were supplied by Sigma Aldrich. Anhydrous acetonitrile (99.8%), acetonitrile (ReagentPlus, 99%), silver trifluoromethanesulfonate (99%), acetonitrile-d3 (99.8 atom % D) were obtained from Sigma-Aldrich. Acetonitrile-d3 (99.8 atom % D) for electrolysis experiments was obtained from abcr GmbH, Karlsruhe. 1,3-Dimethylimidazolium bis(trifluoromethylsulfonyl)imide (99%) was purchased from Iolitec Ionic Liquids Technologies GmbH. Milli-Q water was taken from a Milli-Q Advantage A10 Water Purification System, Millipore (18 M.cm). All chemicals were transferred to the glove box after vacuum drying and were used without further treatment. Additional details can be found in Chapter 2. II- Experimental methods The anhydrous electrochemical preparation, reference electrode preparation, and electrochemical measurement procedures followed the protocols outlined in Chapter 2. By adhering to these standardized procedures, we ensured that the results obtained were accurate and reproducible. Prior to use, the working electrodes were polished with sandpaper until a shiny surface appeared, washed with Milli-Q water, and sonicated in ethanol for 10 minutes, followed by a final sonication in anhydrous acetonitrile (MeCN) for another 10 minutes.
