Abstract: The Mn-Ce/TiO2 catalyst was prepared by the incipient impregnation of instilling nitric acid manganese and nitric acid cerium solution on the surface of the TiO2 particles. Using a fixed bed catalyst reactor and ammonia gas as the reductant，the activation of selective catalytic reduction NO was studied by catalyst prepared in different manganese precursors. And the NO removal rate was also studied under different load sequences，temperatures，load capacities，space velocities，and content of O2，NH3/NO. The result showed that the NO removal rate of catalyst can reached 90%. when the temperature was 160 ℃，Mn∶Ce molar ratio was 8∶1 and load capacity was 18%.
