摘要
以XPS和XRD手段研究了La_(1-x)M_xCoO_3复合氧化物的还原性质,得到还原程度次序为La_(1-x)Sr_xCoO_3>La_(1-x)Ca_xCoO_3>LaCoO_3;相同离子取代系列随x增大,还原容易进行,探讨了取代钴酸镧的氢还原机理。
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.
