Abstract


Kinetic regularities of the electrodeposition of lead dioxide from electrolytes containing polyelectrolytes Drimax 1235 and Magnafloc manufactured by Ciba have been investigated. It was determined that the inhibition of the reaction of electrooxidation of Pb2+ with the decrease of a transfer coefficient without the changing of the mechanism of the process occurs in the presence of polyelectrolytes as additives in the deposition electrolyte. Observed effects depend upon the nature of the polyelectrolyte and probably caused by blocking of active sites on the surface of the growing oxide by adsorbed polyelectrolyte molecules. The use of polyelectrolytes as additives leads to a change in the catalytic activity of obtained materials in the reactions of oxygen evolution and oxidation of 4-chlorophenol.
