| Abstract | Hybrid films composed of chitosan and Keplerate-type polyoxometalate, {Mo72Fe30} (Mo72 VI Fe30 III O252- L102 ca.180H2O, L H2O/CH3COO /Mo2O8/9 n- ), were fabricated on quartz, silicon, and ITO substrates by layer-by-layer (LbL) method. The LbL films were characterized by UV vis spectroscopy, X-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and cyclic voltammetry (CV). UV vis spectra show that the absorbance values at characteristic wavelengths of the multilayer films increase almost linearly with the number of chitosan/{Mo72Fe30} bilayers. XPS spectra confirm the incorporation of chitosan and {Mo72Fe30} into the films. The electrocatalytic reduction of ClO3-, BrO3-, and IO3- by chitosan/{Mo72Fe30} hybrid films in an acidic aqueous solution shows an electrocatalytic reduction activity of IO3-＞BrO3-＞ClO3-. In particular, the modified electrodes exhibited high electrocatalytic activity for reduction of IO3-. |
