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Sr2+取代量与高温、高Sr2+取代量的反应途径不同,这可从化合物的结构、化合物中金属一氧键的标准生成焓的总和、NO还原的表观活化能及化合物上O2的脱附行为等得到解释。

关键词: Sm2-xSrxNiO4, NO还原, CO氧化

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.

Key words: Sm2-xSrxNiO4, NO reduction, CO oxidation
