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.
