Abstract
The electrical conductivity of Н2 – x (NH4) x V9Mo3O32.5 – δ · nH2O xerogel films containing different amounts of ammonium ions and water was measured as a function of temperature. The results demonstrate that, in a wide temperature range, the proton conductivity of the films reaches a maximum atx= 1.5. The activation energy of conductivity in the films, equal to 0.1–0.2 eV at low temperatures, rises upon partial dehydration above 100°C. The possible mechanisms of proton formation and transport are discussed.
