Abstract

A phosphopolyoxomolybdate (P₂Mo₁₈) doped polypyrrole (PPy) modified electrode was prepared in aqueous solution by a one-step method. During the polymerization of PPy, P₂Mo₁₈ acted as both catalyst and dopant. The electrochemical behavior of the PPy/P ₂Mo₁₈ modified electrode before and after the overoxidation of PPy was investigated. Both of these showed a catalytic effect toward bromate. The PPy/P₂Mo₁₈ composite film was characterized by chronoamperometry, cyclic voltammetry, the rotating disk electrode technique, X-ray photoelectron spectroscopy and Raman spectroscopy.
