Effects of SO2 on selective catalytic reduction of NO with NH3 over a TiO2 photocatalyst
The effect of SO2 gas was investigated on the activity of the photo-assisted selective catalytic reduction of nitrogen monoxide (NO) with ammonia (NH3) over a TiO2 photocatalyst in the presence of excess oxygen (photo-SCR). The introduction of SO2 (300 ppm) greatly decreased the activity of the photo-SCR at 373 K. The increment of the reaction temperature enhanced the resistance to SO2 gas, and...

متن کاملIron-doped Mn-Ce/TiO2 catalyst for low temperature selective catalytic reduction of NO with NH3.
The catalysts of iron-doped Mn-Ce/TiO2 (Fe-Mn-Ce/TiO2) prepared by sol-gel method were investigated for low temperature selective catalytic reduction (SCR) of NO with NH3. It was found that the NO conversion over Fe-Mn-Ce/TiO2 was obviously improved after iron doping compared with that over Mn-Ce/TiO2. Fe-Mn-Ce/TiO2 with the molar ratio of Fe/Ti = 0.1 exhibited the highest activity. The results...

Novel iron titanate catalyst for the selective catalytic reduction of NO with NH3 in the medium temperature range.
An iron titanate catalyst with a crystallite phase, prepared by a co-precipitation method, showed excellent activity, stability, selectivity and SO(2)/H(2)O durability in the selective catalytic reduction of NO with NH(3) in the medium temperature range.
