Electrochemical stability and electrocatalysis behaviors of poly(3-methylthiophene) thin film modified electrodes

Abstract

The electrochem. stability of poly(3-methylthiophene) (I) film on a glassy carbon electrode in different electrolyte solns. was studied by continuous cyclic voltammetry. The electroactivity of I film in solns. decreased with second-order kinetics in the presence of ClO4-, BF4-, and NO3-. The rate of degradation of I in aqueous solution was faster than that in acetonitrile solution and decreased in the following order: NO3- (H2O) > ClO4- (H2O) > BF4- (H2O) > ClO4- (acetonitrile). I film was stable in the presence of H2PO4-. I-glassy carbon electrode could electrocatalyze the oxidation of Br- and Cl- and lost its electroactivity rapidly. XPS showed that Cl was bonded covalently onto I after cyclic voltammetric cycles in NaCl solns.
