A Ce-Zr-Mn-Ox(CZM) catalyst has been discovered for selective catalytic reduction of NOxwith NH3in the presence of O2. In this paper, The catalysts of CZM with 10~50 wt% MnO2content and Ce-Zr-O2(CZ) catalyst are prepared by hydrothermal synthesis method. The catalytic activity of CZM catalysts at different temperatures, different space velocities and different ratios of NH3/NO are studied. The results show that the catalyst of CZM with 40 wt% MnO2content yields higher NO conversion at low temperature than others. This catalyst shows nearly 90% NOxconversion in a temperature range of 150°C~250 °C at a space velocity of 53000 h-1.

FeMn/SnxTiO2 catalysts were synthesized by introducing Sn as an additive to modify TiO2 supports, and the Sn doping could improve the SO2 tolerance and low-temperature SCR activity significantly.
