✦ Synopsis

UsingXPS method it is shown t h a t the anodic charge transfer supported oxidation of platinum single crystal electrodes in aqueous 0.1 M HCIO, solution is influenced by the atomic! surface arrangements. The best electrode stability is received for the (111) surface with the largest atomic density in the case reported here.

Mit Hilfe der Rontgenphotoelektronenspektrokopie (XPS) wird gezeigt, dalj die vom Ladungstransport begleitete anodische Oxidation von einkristallinen Platin-Elektroden in wa8riger 0 , l M HClO,-Losung von der Anordnung der Atoine in der Oberflache abhiingt. Die gr6Bte Elektrodenstabilitat ergibt sich fur die ( 1 1 1 ) Oberflache mit der in unserem Fall groaten atoniaren Dichte.

The growth of multilayer oxide films on smooth platinum anodes in O-5 M HISOl has been investigated under the potentiostatic conditions where oxygen was evolved vigorously. The range of anodizing condition covered was : electrode potential, 207-2.22 V(nhe); 20-35°C; duration up to 60 min. The growth
