Abstract

Series of CeSn_0.8W_0.6O_x/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%-CeSn_0.8W_0.6O_x/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.
