简介 To provide a Pt/Au electrode which is used to electrochemically pump O2 out of an O2-containing gas mixture selectively in the presence of other oxygen-containing gas constituents and to provide a simple method of producing such a Pt/Au electrode, a Pt/Au electrode for electrochemically pumping out O2 is described, its surface being impregnated with at least one compound of an alkali metal, an alkaline earth metal or a rare earth metal. A method of producing such a Pt/Au electrode in particular is also described, where the Pt/Au electrode is brought in contact with a solution containing at least one compound of an alkali metal, an alkaline earth metal or a rare earth metal, and the excess solvent is removed.
