A new modified electrode was fabricated by layer-by-layer assembly of multilayer films composed of heteropolyanion (SiW_(12)) and cationic polymer poly(diallyldimethylammonium chloride). The reduction electrocatalytic responses of BrO_3~- and _2NO~- on the modified electrode have been investigated. The result shows that the SiW_(12)-containing multilayer films exhibit remarkable electrocatalytic activities for the reduction of BrO_3~- and NO_2~-. The electrocatalytic effects are enhanced with the increasing layer numbers.
