合成了具有尖晶石结构的锰矿MMn2O4(M = Co, Cu, Zn, Mo)和M10.5M20.5Mn2O4(M = Co, Cu, Zn, Mg)，并测试了其对CO、C3H6和乙苯的催化氧化作用。已经确定了亚锰酸盐的催化活性对阳离子性质的依赖性。含有过渡金属离子（Cu、Co）的尖晶石较活泼。已经建立了亚锰酸盐的催化和吸附性能之间的关系。已经发现晶格氧参与CO氧化成CO2。讨论了氧化的机理。
Manganites with a spinel structure MMn2O4(M = Co, Cu, Zn, Mo) and M10.5M20.5Mn2O4(M = Co, Cu, Zn, Mg) have been synthesized and tested in the catalytic oxidation of CO, C3H6, and ethylbenzene. The dependence of the catalytic activity of the manganites on the nature of the cation has been established. The spinels containing transition metal ions (Cu, Co) are more active. A relation between catalytic and adsorption properties of manganites has been established. The participation of the lattice oxygen in the oxidation of CO to CO2has been found. The mechanism of the oxidation is discussed.
