Oxidation of volatile organic compounds on SBA-15 mesoporous molecular sieves modified with manganese

Catalytic combustion of volatile organic compounds, such as propene, has been studied on manganese modified mesoporous molecular sieves. Powder X-ray diffraction, 29Si nuclear magnetic resonance, nitrogen sorption and transmission electron microscopy show that the SBA-15 mesoporous silica molecular sieve can be modified with manganese using Mn2(CO)10 or Mn(O2CMe)2 without significant distortion of the host structure. The two products were catalytically active in propene oxidation, with SBA-15 modified with Mn2(CO)10 showing significantly higher activity, possibly due to higher Mn content, than SBA-15 modified with Mn(O2CMe)2.
