Preparation of Graphene and Electrocatalysis Oxidation of p-Hydroquinone at Graphene Modified Electrode

doi:10.3969/j.issn.0251-0790.2012.06.028

Abstract

Abstract: The graphene(GN) was prepared by reducing graphene oxide(GO) using ammonia solution, and the electrocatalysis on p-hydroquinone(HQ) was also investigated at graphene-modified electrode(GN/GCE). The molecular structure, interface morphology and electrochemical properties of GN were determined by FTIR, Raman, XRD, SEM, AFM, surface area analysis(BET) and electrochemical methods. The results show that the charge transfer resistance of [Fe(CN)₆]^3-/4- at GN/GCE is 75.0 Ω·cm² decreased by 9 times as compared to that of the bare glass carbon electrode(GCE), indicating that GN has good conductivity. Meanwhile, the oxidation peak potential of HQ has been shifted negatively and its reduction peak potential has been shifted positively, and the peak separation potential(ΔE_p) is decreased by 165 mV with the redox peak currents increasing significantly. It is concluded that the reversibility of HQ improves greatly and GN/GCE holds remar-kable electrocatalytic activity toward HQ. The test method has provided an important inspection for in situ monitoring hazardous matter in food, environment and life fields.
