Abstract

The electron storage and shuttling capabilities of reduced graphene oxide (RGO) have been explored by anchoring two redox couples, methyl viologen (MV2+) and ferrocene (Fc). When an RGO modified glassy carbon electrode (GCE/RGO) was subjected to a cathodic scan, a quasi-reversible reduction of MV2+ was seen indicating a loss of electrons contributed to
