Electrochemical Preparation and Application of PEDOT/Ferrocene Modified Electrode

Abstract

A highly stable and sensitive electrochemical sensor was developed by electropolymerisation of poly (3, 4-ethylenedioxythiophene) (PEDOT) and ferrocene (Fc) on gold electrode for the determination of ascorbic acid (AA). The PEDOT/Fc composite film modified Au electrode was characterized by field emission scanning electron microscope，electrochemical impedance spectroscopy and cyclic voltammetry. Compared with bare electrode, the PEDOT/Fc modified electrode exhibited excellent electrocatalytic activity toward the oxidation of AA.
