摘要：

Selective catalytic reduction of nitrogen monoxide over TiO2 with different mobium loadings (between 0 and 15 wt.%) by ethene in an oxidizing atmosphere was studied. Nb/TiO2 catalyst showed high activity and selectivity for the reduction of NO to N-2. The maximum conversion of NO to N-2 was observed on the Nb (10 wt.%)/TiO2. NO2 and N2O were hardly created at the temperature the selective catalytic reduction of NO to N-2 Occurred. On increasing the concentration of ethene, the catalytic activity for the reduction of NO to N-2 was enhanced. The effect of water vapor on the catalytic activity was studied.
