Catalytic combustion of volatile organic compounds, such as propene, has been studied on manganese modified mesoporous molecular sieves. Powder X-ray diffraction, (29)Si nuclear magnetic resonance, nitrogen sorption and transmission electron microscopy show that the SBA-15 mesoporous silica molecular sieve can be modified with manganese using Mn(2)(CO)(10) or Mn(O(2)CMe)(2) without significant distortion of the host structure. The two products were catalytically active in propene oxidation, with SBA-15 modified with Mn(2)(CO)(10) showing significantly higher activity, possibly due to higher Mn content, than SBA-15 modified with Mn(O(2)CMe)(2).
已在锰改性的介孔分子筛上研究了挥发性有机化合物（如丙烯）的催化燃烧。粉末X射线衍射、（29）Si核磁共振、氮吸附和透射电子显微镜表明，使用Mn(2)(CO)(10)或Mn(O(2)CMe)(2)对SBA-15介孔二氧化硅分子筛进行锰改性时，主体结构不会发生明显变形。这两种产物在丙烯氧化反应中具有催化活性，与用Mn(O(2)CMe)(2)改性的SBA-15相比，用Mn(2)(CO)(10)改性的SBA-15活性显著更高，这可能是由于锰含量更高。
