The sample chamber of the electrochemical cell was filled with 12 mL of 0.1 M n-Bu4NPF6/CH3CN. At first, background electrolyte scans were performed with a freshly polished Pt disc electrode. Afterwards 30 µL of a 10 mM 2H-MoS2 solution in hexane were drop casted on the working electrode, dipped in a 3% ethane-1,2-dithiol solution in acetonitrile for a few minutes and afterwards washed with acetonitrile. Then sample measurements were performed five times in a row with the same parameters as for the respective background scan.
