In the absence of protic electrolytes and solvents, oxygen is reduced in two one-electron steps, first to superoxide ion at a potential of −0.75 V vs. S.C.E. and then to peroxide ion at a potential of −2.02 V vs. S.C.E. The second step is not observed with a platinum electrode. Superoxide ion is oxidized to oxygen at −0.73 V and is reduced to peroxide ion at −2.02 V. Peroxide ion is oxidized directly to oxygen at +0.75 V by a two-electron process. In the presence of a protic electrolyte (0.1 F NH4ClO4) oxygen is reduced in one step to hydrogen peroxide at −0.28 V.The kinetic parameters for the oxygen-superoxide ion electrode reaction are essentially the same for all three electrodes; the average for all determinations is: αna = 0.55; ks,h0 = 10−3. The diffusion coefficients for oxygen and superoxide ion in 0.1 F (Et4)NClO4-DMSO solutions have been evaluated; Do2 = 3.23·10−5 cm2 sec and Do2 = 1.08·10−5 cm2 sec. Mechanisms are proposed for the electrode reactions and for disproportionation reactions that are consistent with the observed experimental data.</div>","PeriodicalId":100778,"journal":{"name":"Journal of Electroanalytical Chemistry (1959)","volume":"12 2","pages":"Pages 90-101"},"PeriodicalIF":0.0,"publicationDate":"1966-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0022-0728(66)80021-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"53128493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
