| 摘 要： | 在具有Ｋ２ＮｉＦ４型结构的Ｓｍ２－ｘＳｒｘＮｉＯ４（ｘ＝０．４，０．５，０．６，０．８，１．０，１．２，１．４，１．５）化合物上进行了ＣＯ催化还原ＮＯ的研究。结果表明，低温、低Ｓｒ＾２＋取借代量与高温、高Ｓｒ＾２＋取代量的反应途径不同，这可从化合物的结构、化合物中金属－氧键的标准生成焓的总和、ＮＯ还原的表现活化能及化合物上Ｏ２的脱附行为等得到解释。

| Abstract: | The catalytic activity of perovskite series Sm2-xSrxNiO4(x=0. 4, 0.5, 0. 6, 0. 8, 1.0, 1. 2, 1. 4, 1. 5) has been studied for the reduction of NO by CO. The results indicate that the route at low temperature and low degree of substitution of lanthanum by strontium is different from that at high temperature and high degree of Sr2+ substitution, which is closely related to the structure of the compounds, to the sum of the enthalpies of the metal-oxygen bonds in the compounds, to the apparent activation energies for the reduction of NO as well as to the behaviour of oxygen desorption from the compounds. |
