Abstract
In this work the bimetallic composites formation via electrochemical co-deposition of Fe(III)Cl-5,10,15,20-tetrakis(4-aminophenyl)porphyrin and Mn(III)Cl-5,10,15,20-tetrakis(4- aminophenyl)porphyrin has been studied. The composites were obtained by superoxide-assisted electrochemical deposition from mixed DMSO solutions with equal concentrations of porphyrins. Spectral analysis of the obtained composites has shown their enrichment with Mn-complexes of porphyrin. Comparative analysis of morphology and electro active surface area, as well as the responses in oxygen electro reduction process on their surfaces has been carried out for individual porphyrins and composites films. A higher catalytic activity has been demonstrated for the films of the bimetallic composites as compared to those of the individual metal complexes.
