The CeO₂, WO₃ and CeO₂-WO₃ (donated as CW) catalysts were prepared by in-situ self-assembly method and used for the low-temperature selective catalytic reduction (SCR) of NO_x with NH₃. The results showed that CW catalysts possessed the most microspore and maximum pore volume and larger specific surface area with the addition of WO₃, resulting in the improvement to the catalytic performance. Besides, the interaction of Ce and W was improved by the introduction of WO₃, which could increase the amount of Ce³⁺ and O_α. Meanwhile, the enhancement of weak and medium strong acid sites was caused by the introduction of WO₃. Thus, CW catalyst showed the best SCR activity and its NO_x conversion at the value of 100% maintained in a wide temperature window ranging from 250 to 400 ℃.
