Oxygen reduction characteristics on pyrolytic graphite electrodes modified with electro-polymerized salen compounds

摘要

Electro-polymerized cobalt salen compounds on pyrolytic graphite electrodes were first tested as oxygen reduction catalysts in aqueous solutions of various pH. From electrochemical measurements it was revealed that although in acidic media the catalyst performance deteriorated, the performance in neutral and basic media was relatively good as compared to that of platinum, the best catalyst for this reaction.
