Photocatalytic Reduction of NO in the Absence and Presence of Hydrocarbons over Ti-, V-, Mo-MCM-41 |
초록 |
The photocatalytic reduction of NO into N2 in the absence and presence of hydrocarbons were investigated on Ti-, V-, and Mo-MCM-41 mesoporous molecular sieves. It was found that Ti-MCM-41 shows much higher photocatalytic reactivity for the direct decomposition of NO into N2 and O2 than V- and Mo-MCM-41. In contrast to Ti-MCM-41, the reactions of NO into N2 on V- and Mo-MCM-41 were remarkably enhanced in the co-existence of propane. From photoluminescence, ESR, and photo-adsorption measurements, the origin of the sharp difference observed on Ti-MCM-41 as compared to V- and Mo-MCM-41 in this reaction could be attributed to the low reactivity of the charge transfer excited Ti-oxide species for the activation of propane as the first step of the reduction of NO with propane. |
