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

Abstract

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 Mn 2(CO) 10 or Mn(O 2CMe) 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 2CMe) 2.
