| Abstract: | Vanadium-substituted heteropolytungstate anions(H3PW6V6O6-40, denoted as PW6V6)-containing multilayer films have been fabricated on the 4-aminobenzoic acid(4-ABA) modified GCE surface by alternating deposition with a quaternized poly(4-vinylpyridine) partially complexed with osmium bis(2,2-bipyridine)(denoted as QPVP-Os). Surface plasmon resonance(SPR) spectroscopy and cyclic voltammetry(CV) have been used to characterize the growing behavior of the as-prepared multilayer films. It is shown that the multilayer films are uniform. The average thickness for a bilayer of QPVP-Os/PW6V6 in the multilayer films is 2.88 nm. The electrocatalytic activities of the multilayer films for the reduction of BrO3- and NO2- have been investigated. |
