Measurements were performed under the same inert conditions in the same full-glass-cell with the same electrolyte solution, CE and RE, only the WE was different: A beforehand mentioned Pt interdigitated electrode with a gap width of 5 µm between the electrode arrays and total channel length of 3.373 m (Metrohm G-IDEPT5) was used. Both arrays are independently controlled by the two working electrode channels of the CHI760E bipotentiostat. All measurements were initiated at the OCP at -0.4 V vs. Fc/Fc + . Before the 2H-MoS2 nanosheet coated IDEs were measured, an uncoated sample was investigated with the same parameters to check whether there were any contaminations in the electrolyte solution.
