Seeking to compare reactivity of these nanoparticle coated electrodes in the cross-coupling with known reactivity of similarly functionalized electrodes, glassy carbon disk electrodes were also functionalized. Nanoparticle deposition on this disk electrode was validated by anodic stripping voltammetry (Figure ) and S/TEM imaging (See SI, Figure ). The reduction potential of benzyl chloride is known to shift 500 mV more positive on a silver-nanoparticle decorated electrode and such behavior was observed on our nanoparticle-coated disk. Cyclic voltametric studies of reductively labile components of the cross coupling, NiCl2(bpy) and RAE 7, revealed no significant differences in the onset of reduction of these two species at the functionalized electrode in comparison to glass carbon surfaces (See SI, Figures ).
