Highly oriented pyrolytic graphite (HOPG) and graphene grown on Ni (Ni-Gra) or Cu (Cu-Gra) by chemical vapour deposition were modified with thick anthraquinone (AQ) films (7−60 nm) by redox grafting of the pertinent diazonium salt. Glassy carbon (GC) electrodes were used for comparison. The AQ-modified GC electrodes showed excellent blocking properties towards the Fe(CN)63−/4− redox probe, although it was noted that in the case of Ni-Gra and Cu-Gra, the blocking ability depended strongly on the…
