The novel Fe-Mn-Ti compound catalysts were prepared by co-precipitation, based on the lower price and smaller surface area TiO 2 . Then the cause of high catalytic activity which was represented by the compound catalyst was discussed. X-ray diffraction (XRD) was used to characterize the active phase and its results showed that a new Fe 0.33 Mn 0.05 Ti 2.52 O 5 phase was generated for Fe-MnO X -Ti. The Fe 0.33 Mn 0.05 Ti 2.52 O 5 played a decisive role on the process of low-temperature SCR. However the effect of catalyst was not observed when the temperature was up to nearly 300°C. Based on the above statement, above 90% conversion of NO X on the Fe(0.5)-MnO X -Ti(400) (the molar ratio of n(Fe)/[n(Fe)+n (Mn)]=0.5 and calcined at 400°C) was achieved among 180°C to 280°C.
