Process for preparing iridium oxide film

摘要

The present invention provides a process for preparing an iridium oxide film which comprises evaporating iridium and carbon by electron beam or sputtering to prepare an iridium-carbon composite film, heating said composite film in an oxidizing atmosphere to form a thermally oxidized iridium oxide film, and continuously applying an alternating potential to said iridium oxide film in an aqueous solution to conduct electrolytic oxidation.
