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 order of La_ (1-x) Sr_xCoO_3> La_ (1-x) Ca_xCoO_3> LaCoO_3 was obtained by means of XPS and XRD. The same series of ions substituted with x Increase, restore easy to carry out to discuss the replacement of lanthanum cobalt hydrogen reduction mechanism.
