a Experimental setup. b Schematic depicting the removal of the interference from the gold film, which was passivated by a self-assembled monolayer (SAM) of 1-octadecanethiol molecules. Ru(III) and Ru(II) represent [Ru(NH3)6]3+ and [Ru(NH3)6]2+, respectively. c Typical images displaying the surface charge density and electrocatalytic activity of monolayer MoS2.
