| 中文摘要 | two systems of mixed oxides, la2-xsrxcuo4 +/- lambda (0.0 less than or equal to x less than or equal to 1.0) and la(2-x)tn(x)cuo(4 +/-) (lambda) (0.0 less than or equal to x less than or equal to 0.4), with k2nif4 structure were prepared. the average valence of cu ions and oxygen nonstoichiometry (lambda) were determined by means of chemical analysis. meanwhile, the adsorption and activation of nitrogen monoxide (no) and the mixture of no + co over the mixed oxide catalysts were studied by means of mass spectrometry temperature-programmed desorption (ms-tpd). the catalytic behaviors in the reactions of direct decomposition of no and its reduction by co were investigated, and were discussed in relation with average valence of cu ions, a and the activation and adsorption of reactant molecules. it has been proposed that both reactions proceed by the redox mechanism, in which the oxygen vacancies and the lower-valent cu ions play important roles in the individual step of the redox cycle. oxygen vacancy is more significant for no decomposition than for no + co reaction. for the no + co reaction, the stronger implication of the lower-valent cu ions or oxygen vacancy depends on reaction temperature and the catalytic systems (sr- or th-substituted).
