Electrochemically Reduced Graphene Oxide Film Modified Electrode for Detection of Hydrogen Peroxide

Abstract

A novel electrochemical method was proposed for detection of hydrogen peroxide (H2O2) based on electrochemical reduction of graphene oxide (GO) modified glassy carbon electrode (GCE). The electrochemically reduced graphene oxide (RGO) was characterized using cyclic voltammetry (CV). Under the optimized conditions, the RGO modified GCE showed much wide linear range for H2O2 from 2.0 to 600 M with the detection limit of 0.67 M (S/N = 3). The proposed method is simple, low-cost and convenient and will be a promising alternative for H2O2 sensing.

A Highly Sensitive Carbendazim Sensor Based on Electrochemically Reduced Graphene Oxide

“…23 Since electrochemical reducing method was proposed by Guo,24 electrochemically reduced graphene oxide and its nanocomposite have been applied in the detection of p-aminophenol 17 , pyrosine 25 , dopamine 26,27 , glucose 28 , hydrogen peroxide. 29 To the best of our knowledge, the use of electrochemically reduced graphene oxide modified electrode for the electroanalytical detection of carbendazim has not been reported.…”
