Abstract:

Electrochemical oxidation of formic acid at polyaniline films modified by palladium microparticles (PAN(Pd)) has been studied using electrochemical techniques, XPS and Raman spectroscopy. It has been shown that because of the interaction between Pd and PAN, Pd microparticles can be stablized in the PAN films in the potential region from -0.2V to +0.9V, and the oxidation of formic acid can prevent the degradation of the PAN, resulting in high stability of the PAN(Pd) electrode and its electrocatalytic activity for oxidation of formic acid.

Key words: Electrocatalysis, Polyaniline, Palladium microparticles, Formic acid
