中文摘要	adsorption and activation of small molecules no, co and co+ no on lasrcuo4, la2cuo4 and la1.7th0.3cuo4 which are typical samples in the sence of nonstoichiometric oxygen(lambda) anrong the series of la2-x(srth)(x)cuo4 +/-lambda mixed oxide catalysts were studied by means of ms- tpd (tpsr ), xrd, chemical analysis and so on. it was shown that the adsorption amount of no can be correlated with the content of oxygen vacancy while the types and strength of adsorption of no could be related to the oxidation state of the metallic ion. it was also found that co molecule was first converted into co32- and then desorbed in the form of co2 at high temperature during the adsorption and desorption of co on the mixed oxide with oxygen vacancy. the fact that the profiles of tpd(tpsr) of no in co-adsorption of no+co and in single no adsorption are similar shows that the adsorption of no molecule not only has some priority to that of co but also is stronger than that of co. it seems that the adsorption of no plays a dominate role in the activation and decomposition of no.
