摘要：

The reduction of ClO4- ions was studied in an acid medium at Re layers electrodeposited onto Pt and Au supports from ReO4--containing supporting electrolytes. It was shown that the electroreduction leading to the formation of Cl- ions takes place in a relatively wide potential range (0-300 mV/RHE); however, no real steady state polarization measurements could be carried out owing to the self-inhibition caused by adsorption of the reduction product (Cl- ion) and the change of the surface state of the electrode. The role of the competitive adsorption of anions was demonstrated by a radiotracer study of the adsorption of labelled HSO4- ions. The problems connected with the interpretation of the experimental results are discussed.
