摘要：

In the present work a comparison has been tried between the proton-exchange properties of thermally prepared films of ruthenium oxide and iridium oxide, by means of nuclear reaction analysis and a radiometric method based on exchange of tritium-labelled species. Hydrogen concentration depth-profiles have been determined before and after anodic polarization. Results indicated that a thickness of about 50 nm below the surface is involved in the exchange process. Larger amounts of hydrogenated species were found in iridium oxide samples. Tritium-exchange experiments confirmed these data. Comparison with electrochemical results has also been carried out.
