下面是这篇文章的一些细节，希望有帮助。 Accession number: 86110169343 Title: INFLUENCE OF PLATINUM (PHASE) OXIDE ON THE ELECTRODE KINETICS OF THE MANGANESE(III)/MANGANESE(II) AND CERIUM(IV)/CERIUM(III) REDOX COUPLES IN SULPHURIC ACID. Authors: Randle, T. H.; Kuhn, A. T. Author affiliation: Swinburne Inst of Technology, Hawthorn, Aust Serial title: Electrochimica Acta Abbreviated serial title: Electrochim Acta Volume: v 31 Issue: n 7 Issue date: Jul Publication year: 1986 Pages: p 739-744 Language: English ISSN: 0013-4686 CODEN: ELCAAV Document type: Journal article (JA) Abstract: The kinetics of the Ce(III) Ce(IV) and Mn(II)/Mn(III) redox reactions (both oxidation and reduction) were followed at a rotating Pt disc electrode, on which known amounts of platinum oxide (type II) had been formed. Oxide film inhibits both anodic and cathodic reactions, but to different extents. There is no systematic decrease in i//0 with increase in film thickness suggesting that electron tunnelling is unimportant under these conditions but that electron exchange takes place with the oxide itself. The inhibiting effect of type II oxide is seen even when it is present in sub-monolayer amounts, and this and other effects suggest that the overall behavior of the system cannot be simply represented, for example in terms of a semi-conducting oxide.
