钙钛石型复合氧化物LaMn_yCo_（1－y）O_3上的一氧化碳氧化

讨论了Ｍｎ－Ｃｏ二元Ｂ位复合钙钛石型氧化物ＬａＭｎｙＣｏ１－ｙＯ３对ＣＯ氧化的催化能及其与催化剂的固体物理化学性质之间的关系。从活化能和指前因子互补的观点讨论了影响催化活性的主要因素。Ｍｎ，Ｃｏ离子之间的氧化还原性质的不同会影响催化剂的结构、过渡金属离子的状态和氧的吸附性能，进而影响ＣＯ氧化反应的催化活性。在富站区，催化活性主要取决于金属钻离子的状态，富锰区主要与锰离子和催化剂的缺陷结构有关。

Oxidation of Carbon Monoxide on Perovskite Type Multiple Oxide LaMa_yCo_(1-y)O_3

The catalytic behaviour of perovskite type muhiple oxide LaMnyCo1-yO3 for CO oxidation and the relationship between the catalytic property and solid state physicochemical properties of the catalysts are discussed, and the main factors influencing the catalytic atcivity are also discussed from the point of view of compensative relation between the activation energy and pre-exponential factor. The difference between the redox properties of Mn, Co ions could ifluence on the catalyst structure, the state of transition metal ions and the oxygen absorption property, hence, the catalytic activity of catalysts for CO oxidation. In Co-rich region, the catalytic activity is dominated by Co ion state and in Mn-rich region by Mn ion state and the defect structure of the catalysts.
