In order to achieve rapid detection of low concentration hydrogen peroxide (H2O2),a non-enzymatic H2O2 electrochemical sensor was constructed by using glassy carbon electrode as substrate,Nafion as selective coating material,electrochemical reduced graphene oxide and electrochemical polymerized polyaniline complex (ERGO/PANI)as modifier.The microstructure and molecular structure of the modified electrode was characterized by SEM and raman spectroscopy.The electrochemical properties of the modified electrode and its response to H2O2 were studied by electrochemical impedance spectroscopy (EIS) and cyclic voltammetry.Results shown that the constructed PANI/ERGO-NF/GCE electrode exhibited excellent electrocatalytic performance for the determination of H2O2.The proposed sensor displayed a wide linear range of 1.00～5.00μmol/L,a limit of detection (LOD) of 0.1μmol/L.Moreover,the sensor shown outstanding stability,reproducibility and anti-interference ability.
