Abstract
Graphite-supported polyaniline films (PANI) containing rhodium particles were obtained by two procedures: metal electrodeposition on a prepared PANI film and electropolymerization. The adsorption/desorption and electrowinning of hydrogen on these films were observed for both types of synthesized composite films. PANI/Au composites were synthesized using the PANI films deposited onto a gold electrode. High anode potentials were further applied to the electrode in the presence of chloride ions, leading to a dissolution of gold and its transfer to the films during subsequent electroreduction. The amounts of the chloride complexes of gold formed in this procedure were determined by cyclic voltammetry of their electroreduction.
