Abstract

In this work, polypyrrole films with ferrocenecarboxylic acid incorporated (PPy/FCA) were prepared on a glassy carbon (GC) electrode in chloroform as an aprotic solvent with low dielectric constant, convenient for the preparation of the films by a precipitation mechanism. The electrochemical behaviour of the PPy/FCA-coated GC electrode was studied by cyclic voltammetry in aqueous solution with low pH. The results obtained show that the electrochemical response of FCA incorporated in polypyrrole is consistent with a reversible surface oxidation. An obvious electrocatalytic effect of PPy/FCA on the oxidation of ascorbic acid is observed in aqueous solution.
