摘要：

The usefulness of solid electrolyte potentiometry in the case of oxidic catalysts has been shown by the combined kinetic and electrochemical study of the partial oxidation of propene on copper oxides. The potentiometric determination of the oxygen activity in the catalyst under working conditions indicates the thermodynamically stable phase-composition, the selectivity measurements allow the simultaneous verification if the thermodynamically stable phase has really been formed. The results show clearly that the stability limits of the existing solid phases are shifted under the influence of the additive.
