Abstract: The reduction of La1-xMxCoO3 has been studied by XPS and XRD. The extent of reduction of the perovskite oxides has been obtained as: La1-xSrxCoO3 > La1-xCaxCoO3> LaCoO3; for the same substitution cation, the extent of reduction increases with x. The reduction mechanism of La1-xMxCoO3 was discussed.

Key words: Perovskite oxides, Reduction, XPS
