The influence factors on CeSn0.8W0.6Ox/TiO2 for catalytic removals of NO, CO and C3H8

[Display omitted] Series of CeSn0.8W0.6Ox/TiO2 catalysts were tested for selective catalytic reduction of NO and for synergistic catalytic removals of CO and C3H8 from diesel engine exhaust. Results revealed that catalyst 12%-CeSn0.8W0.6Ox/TiO2 calcined at 500°C exhibited the optimal catalytic performance for NH3-SCR of NO. The catalyst obtained more than 90% NO conversion at a wide temperature range of 252–456°C. Both CO and C3H8 could be oxidized into CO2 by the optimized catalyst. Moreover, excellent redox property, rich surface acidity and big specific surface area were the promotional factors for good catalytic performance in catalytic removals of NO, CO and C3H8.
