研究了锰基和铁基钙钛矿的固态性质对氧化条件下丙烯选择性催化还原一氧化氮活性的影响。用锰取代固溶体La0.6Sr0.4Fe1−yMnyO3±δ(0≤y≤1)中的铁，用锶取代固溶体La1−xSrxMnO3+δ(0.05≤x≤0.50)中的镧，表明钙钛矿的催化活性主要取决于过渡金属的氧化还原性能和氧空位数。
The influence of the solid state properties of manganese- and iron-based perovskites on the activity for the selective catalytic reduction of nitric oxide with propene under oxidizing conditions has been investigated. By substituting manganese for iron in the solid solution series La0.6Sr0.4Fe1−yMnyO3±δ (0 ≤ y ≤ 1) and by substituting strontium for lanthanum in the solid solution series La1−xSrxMnO3+δ(0.05 ≤ x ≤ 0.50) it is shown that the catalytic activity of the perovskites depends mainly on the redox properties of the transition metal and on the number of oxygen vacancies.
