摘要：

The oxygen reduction kinetics have been investigated in different acid media by the RRDE and voltammetric techniques on iron naphthalocyanines. Better activity and stability were found in perchloric acid solutions. In most cases adirect four-electron pathway was shown. The reaction mechanism appears to be associated with a redox couple which should involve the central ion. Correlations can be established between the potential of the redox couple and the activity as seen by the RRDE technique.
