- Аннотация: The electrochemical behavior of Pd-PAN systems, where PAN stands for polyaniline, is studied. The systems are formed by electrodepositing palladium onto a PAN-GC electrode (GC, for glassy carbon). It is shown by atomic force microscopy that some palladium particles are deposited directly on the PAN surface even at potentials of low electroconductivity of PAN. Properties of Pd-PAN coatings formed by this technique are compared to those of Pd-PAN systems formed by cycling the potential of a GC electrode in a PdSO4 + aniline solution, which were studied earlier. Redox characteristics of PAN and the degrees of the promotion of the electrocatalytic activity in the HCOOH oxidation reaction differ in the two systems. The differences are attributed to specific features inherent in the formation of the mixed coating, in particular, to differences in the degree of contact of palladium crystallites with PAN. The PAN degradation in the Pd-PAN systems is shown to be linked mainly to the PAN oxidation, which is catalyzed by the incorporated palladium particles.
