Abstractdc.description.abstractMultilayer electrostatic assemblies described as {[FeTPyP(Crphen2Cl)4]8+/SiW12O404−}ni{[FeTPyP(Crphen2Cl)4]8+/SiW12O404−}ni and {[NiTPyP(Crphen2Cl)4]8+/SiW12O404−}ni{[NiTPyP(Crphen2Cl)4]8+/SiW12O404−}ni, where TPyP = 5,10,15,20-tetra(4-pyridyl) porphyrin, phen = 1,10-phenanthroline, SiW12O404− = silicontungstate and ni = number of multilayers, were assembled onto different electrodic surfaces. The modified electrodes were constructed using the layer by layer methodology. UV-Vis spectroscopy, scanning electron microscopy (SEM), and cyclic voltammetry were used for the electrodes characterization. The electrocatalytically reduction of oxygen in aqueous solution was driven with these electrodes. In the oxygen reduction, rotating ring-disk and cyclic voltammetry techniques revealed a synergic effect between the cationic porphyrin and SiW12O404−. The synergism is related to the number of multilayers, the porphyrin complex employed, inner electroactive process across assemblies and the overpotential applied in the electrochemical process.en_US
