I want to reduce graphene oxide sheets to reduced graphene oxide on glassy carbon / platinum electrode through cyclic voltammetry.
Zhu. et.al Analytical Methods, 2012, 4, 2935
they prepare erGO from exfoliated GO using 0.1 M PBS pH 4.6 potential range 0 to -1.5V.
actually I prefer electrochemical reduction because I need a thin film of reduced graphene oxide on my electrode surface.
I have reduced graphene oxide by hydrazine hydrate..but the rGO is difficult to suspend in solution and its does not form a uniform film on dip casting the suspension of rGO on electrode surface.
At glassy carbon electrode at pH 7, the GO reduction will occur between -0.7 V to -1.25 V vs Ag/AgCl electrode. The GO reduction is pH dependent reaction. U can refer our paper, "Fabrication of electrochemically reduced graphene oxide films on glassy carbon electrode by self-assembly method and their electrocatalytic application", J. Phys. Chem. C, 2013, 117 (8), pp 4326–4335.
