Abstract: Electrochemical polymerization behaviors of luminol at GO/Nafion/GCE and GN/Nafion/GCE were studied by cyclic voltammetry based on the excellent conductivity of grapheme and good electrochemiluminescence performance of luminol.The effects of modified solution composition and initial potential on the electrochemical polymerization behaviors of luminol were investigated.K3[Fe(CN)6] was employed as electrochemical probe to study the conductivity of modified electrode before and after polymerization of luminol.The results showed that the polymerization process of luminol was more likely to occur on GO/Nafion/GCE under more negative potential,which displayed stronger electrocatalytic ability toward K3[Fe(CN)6].

Key words: graphene oxide, Nafion, luminol, electrochemical polymerization
