摘要：

A series of tungsten modified MnO(x)-CeO(2) monolith catalysts were prepared and used for selective catalytic reduction (SCR) of NO by NH(3) in the presence of O(2). The experimental results showed that the SCR performance and SO(2)-resistant ability of MnO(x)-CeO(2) were greatly enhanced by the introduction of tungsten. The catalyst containing 10% WO(3) showed the highest NO conversion in a wide temperature range of 162-374 degrees C. The highly dispersed or amorphous tungsten oxide and the strong interaction between tungsten and MnO(x)-CeO(2) should be the reasons for the excellent performance of the catalyst containing 10% WO(3).
