内容記述 | Ga2O3-Al2O3 prepared by sol-gel method (Ga2O3-Al2O3(S)) exhibited excellent activity for the selective reduction of NO withpropene, compared with Al2O3, Ga2O3 and impregnated Ga2O3/Al2O3 (Ga2O3/Al2O3(I)). X-ray diffraction (XRD) and extended Xrayabsorption fine structure (EXAFS) measurements of Ga2O3-Al2O3(S) revealed that a composite oxide in the form of [GaxAl(1-x)]2O3 (x<1) is uniformly formed by substitution of Ga3+ for Al3+ in the Al2O3 lattice. New reaction sites created by a synergisticeffect between Ga and Al ions (represented by “Ga-Al sites”) in a composite oxide [GaxAl(1-x)]2O3 (x<1) would be proposed toparticipate as catalytically active sites for NO reduction by propene. On the basis of the experimental results of kinetic studies,in situ diffuse reflectance FT-IR spectroscopy and GC-MS analysis of minor by-products, the following reaction mechanism hasbeen proposed; NOx (NO2- and/or NO3-) species formed by NO+O2 reaction on the catalyst surface reacts with C3H6-derived species(probably, allyl species), leading to the formation of -CN and -NCO species via organic nitro compounds (R-NO2). The -NCOspecies is hydrolyzed to compounds including amino groups (amines) with traces of water, and then amines react with NOxadspecies and/or NO2 to produce N2. | |||||
